Amazon, eBay, eBay - What Are Some of the Most Common Integrations?

It's a problem that existed in Australia, I think early on. Then we discovered the same problem exists in Europe,. It's a little easy sometimes if you're a seller in just one marketplace... But then it gets a nightmare if you start adding on different places because everyone's going to record transactions in a slightly different way. The fee structure might be a little bit differently. What are some of the most typical integrations that people are using outside of Amazon, eBay? What else are you seeing a lot of? Yeah, yeah. I can't see that all in one place.
