KRE Prime review for CedCommerce Walmart Connector

I am baffled by the application developer's request for an additional $299 to fix a problem with their application. Given that I have already paid $190 for its use, this demand seems unjust. The issue of the application incorrectly flagging non-duplicate SKUs as duplicates is something they should address. While the application fulfills its basic functions, there are still bugs and issues that require resolution.
