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.

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.

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.

TOTAL SCAM DO NOT INSTALL! It's a way to steal your customers. Not only do they have no way to add your brand referral code (because why would I pay Amazon a referral fee when I'm using my own website to direct my own traffic- ARE YOU SERIOUS?!?!), customer service won't even let me request the feature. You are better off creating your own link with the brand referral code and adding it to your website, DO NOT LET THEM STEAL YOUR CUSTOMERS WITH THIS APP!
Hi Stamen, thank you for taking the time to leave a review. It seems there may have been a misunderstanding about our program. Buy with Prime is designed to help brands grow your direct-to-consumer (DTC) business and increase customer conversion by offering fast, free delivery on your site. Shoppers should check out using the Buy with Prime button on your DTC site, not on Amazon.com. As such, the brand referral code is not meant to be added when using Buy with Prime. We'd be happy to assist you with any further questions, please sign in your Buy with Prime account and contact our team!

We’ve had a deeply disappointing experience with this app. Despite submitting multiple tickets regarding display issues, the responses have been unsatisfactory. The most recent reply suggested that we are missing some CSS; however, the app fails to show any output, even without CSS. The Amazon Reviews app has some straightforward customization options available; why doesn’t Amazon Prime? After months of trying to resolve these issues, we feel like we’re going in circles with no clear resolution or accountability from the support team. In today’s tech landscape, an app should be plug-and-play. Given Amazon’s vast resources, it’s unacceptable that we have to jump through hoops for something as basic as CSS functionality, which is obviously not the reason the app doesn't print ANY output! We’re left wondering if there are any plans to address these ongoing issues. Overall, this has been a very unsatisfactory experience
Thank you for taking the time to leave a review, and I am sorry to hear about your experience. I am aware that our Support team had multiple correspondence with you and eventually helped you get set up on the widget instead of the Shopify app. I wanted to let you know that we have shared your case and feedback with our Product team so that we can continue to improve the product experience for merchants like you. Again, thank you for choosing Buy with Prime!

Once we connected this app and matched products, we were no longer able to create Draft orders in Shopify containing these products even though we had inventory in or non-Amazon location. For this reason we cannot use the app. Amazon support was lacking. The installation call was quick, but no testing was done.
We're sorry to hear the experience wasn't up to your expectations. We would like to connect you with our team for more support and hope to make things right and get you up and running with Buy with Prime! Please contact us at [email protected]

Installed the app to find product reviews/ratings from Amazon can't be brought over to my Shopify store - have not been integrated (yet ... according to a support agent). This was 99% of the value proposition for me. When this feature is available I will try it again and may reconsider my review.
Thanks for your review, StarPlus2 . We're sorry the app functionality currently doesn't live up to your expectations, and appreciate the feedback as we are always looking for ways to improve the app. We'll let you know as we start to support new features.
