Expandly

Well, I tried it, because I want a way to pull eBay and Etsy orders, into my Shopify dashboard.

Instead, it looks like Expandly creates it's own dashboard, and wants to pull everything into it. The App isn't really integrated into Shopify. When you click Apps, and then select Expandly, all it does, it take you over to Expandly's website to do all your work.

So that means over in Expandly, I need to add USPS, Fedex and UPS.
Well, when it showed me the list of postal carriers, USPS isn't in the list.

I can only give it 2 stars, because it doesn't support USPS, nor did it make it clear that it's not integrated INTO Shopify.
