MCF / Buy with Prime has saved my life as a business owner who is too busy to pack orders for my website. The product catalog syncs seamlessly. We have it running in the US and now we just launched MCF Canada and this is the best thing to have ever happened for our business. Thank you Wayne and team for serving us. LOVE IT!
Thank you so much! We're so happy the app is serving you well and helping you grow your business!

Worked as intended. I was enrolled in a pilot to test additional features and the onboarding and communication was great and responsive.
Thank you so much! We're so happy the app is serving you well and appreciate your participation and activation of the additional features!

At first, we struggled to get the app working and installed and uninstalled it a few times. But once we followed the basic setup instructions properly, it worked flawlessly. Previously, we were manually entering order details to fulfil orders through Amazon MCF. Now, every time we get an order in the UK or the US, we just click a button in Shopify. It has completely changed our workflow and allowed us to focus on growing the business instead of managing fulfilment. We were even thinking about setting up our own warehouse, but now 90% of our shipments go through Amazon services via this app.
Thank you so much! We're so happy the app is serving you well in the US and UK. We're also making additional countries available in April if applicable to your business.

Isn't working anymore.
Thank you for taking time to share feedback and surface this issue. Our team investigated, found the edge case that was causing the error, and delivered a fix. We validated that the app is working correctly on your store and would like to invite you to confirm and continue your operations. Thank you again and please let us know if we can help in any other way.

The app is currently unusable. It is stuck indefinitely on "Loading catalog data in progress." After inspecting the console, I found a major authentication flaw in your API connection: {"message":"1 validation error detected: Value null at 'shopifySessionToken' failed to satisfy constraint: Member must not be null"}. How is it possible that the session token is null when the connection is through Shopify's own platform? Furthermore, the API response confirms that the operation bulk_fulfillment_update for my domain (ayaecofashion.myshopify.com) does not exist. This lack of maintenance is directly affecting my sales and inventory management. Please address this backend failure immediately.
Thank you for taking time to share feedback and surface this issue. Our team is actively looking into resolving it, and we will updated as soon as we can when fixed. 2/19 - Thanks you again for sharing feedback and letting us know about the issue. We have resolved it and would like to invite you to use the app - please let us know how we can help get you started.

Why is shipping speed mapping not available?
Thank you for taking the time to share your feedback. Shipping speed mapping is available in the app: 1. On the app home screen, select 'Configure shipping options'. 2. At the bottom of the shipping options page, you'll see all shipping rates you've configured for your store (across all shipping profiles). For each rate, you can select the MCF speed you'd like to apply by opening the drop-down menu in the 'Shipping speed' column. Please don't hesitate to reach out to our support team directly if you have any additional questions or would like more guidance.

I was excited about this app as it promised to simplify my fulfilment process. I’ve used MCF before and expected this to remove the need for manually entering customer details. Instead, orders are sent to Amazon but remain stuck in “processing” and never get fulfilled, an issue others have also raised. Seller Support has been extremely poor — a 45-minute investigation resulted in generic responses and no resolution.
Thank you for taking the time to share your feedback.We appreciate that you are considering our app for simplifying your fulfillment process - that's exactly what the app was built to do. There should not be any need to input customer details manually; relevant customer details are automatically funneled from Shopify order management. Our team looked into the order placed from your store on Feb 4 and found that it was cancelled manully via your Amazon account on Fe 6 before it could be shipped and delivered. We have also initiated an investigation into the support case to understand why it took so long and did not resolve your issue - we are committed to improve and make sure this experience does not occur again for any merchant. Please don't hesitate to reach out again if you have any additional questions or concerns. We appreciate your business and your feedback.

i believe it's just for US market, not Canada.
Thank you for your review, we appreciate the feedback. Please stay tuned in early 2026 as we launch in additional countries - including Canada. If you have any further questions, please don't hesitate to reach out to our support team directly.

I was really excited to use the MCF Fast Badge for my Shopify store, but at first it wouldn’t appear on my live product page—even though it showed correctly in preview. I tried everything: matching SKUs, checking inventory, adjusting permissions, reinstalling, and even having Shopify reindex the page. Nothing worked initially. However, Amazon has since fixed the issue, and the Fast Badge now displays perfectly on my site. Support was responsive throughout the process, and I appreciate that the team followed through and resolved it. The feature works exactly as promised and is a great addition for improving conversions. Very happy it’s functioning properly now. Highly recommend!

We are pleased to inform you that our technical team has successfully identified and resolved the badge display issue you experienced. We appreciate your patience during the resolution process and value your feedback, which helps us improve our services. Please let us know if you need any further assistance.

As with any Amazon's product, the support is awful. Currently the app is sending fulfillment requests to Amazon, but MCF does not accept requests, nor does it provide any notification updates or support options. Amazon seller central support asks for Amazon MCF order number to proceed, which I don't have because the requests are not being received by Amazon.
Thank you for taking the time to share your feedback. We understand your concerns and want to let you know that our team addressed the issue, confirming full functionality. Your feedback helps us continuously improve our processes to better serve all our merchants. If you have any further concerns, please don't hesitate to reach out to our support team directly.

This required a bit of help from support but overall this will be much easier to manage, thanks to the Amazon team for maturing this from the widget code to this baked in shopify app! 5 stars

Amazon's Team is highly supportive and responsive. Learning some of the settings here and hiccups has been a challenge when the app was brand new but Amazon in typical fashion supported us and we are running smooth now. This app is highly beneficial to our company.

As the team behind windshieldwipers.com, we can confidently say that integrating the Amazon Multi-Channel Fulfillment (MCF) and Buy with Prime Shopify app has been an absolute game-changer for our business! The setup was incredibly straightforward, with a seamless three-step connection process that had us up and running in no time. The app automatically syncs our Shopify catalog, making product management a breeze. The Buy with Prime feature has elevated our customer experience to new heights. Offering fast, reliable Prime shipping has given us a competitive edge, and our customers love the smooth checkout process. We've noticed a significant boost in trust and conversions since implementing it. Plus, Amazon MCF has streamlined our fulfillment process, allowing us to focus on growing our business rather than worrying about logistics. The support team is top-notch, always ready to assist with any questions or issues. This app is a must-have for any Shopify store looking to scale efficiently and provide a premium shopping experience. We couldn't be happier with the results! Highly recommend to any e-commerce business aiming to level up!
Thank you for your kind words! It makes our day to know it's making a difference for you. We’re always working to make it even better, so if you ever have ideas or questions, don’t hesitate to reach out!
