Petal Garden, Inc. review for CBB Shipping Rates Calculator

This is one of the first apps I installed for our store, it's a must if you're shipping and have multiple shipping options. The only problem that comes up is that if a customer selects an upgraded shipping option, it doesn't carry over to Checkout. This isn't any fault of the app, it's all on Shopify. Also, their support is great. Had an issue on a Sunday afternoon and they were right on top of it, and it was a simple fix.
