CedCommerce Amazon Channel

Very good - having used Marketplace connect for 12+ months and then making the move because it simply wasn't up to it, CedCommerce is much better. Yes there's still a few bugs but support is excellent - that's a key diff.

Marketplace connect just didn't bother replying in the end, so they lost my business and my recommendation. So if you sell on Amazon and want your products to list correctly, I recommend this app.
