Good to hear from you Vickie. I did try Vendio when Auctiva's rates were new. It wasn't bad but the act of changing and learning another new thing cuts into our profits.
If it works for Amazon and you can actually list both at once it might be worth it in the end.
When I tried Auctiva Commerce I thought I was going to be able to take the same listing that went to Ebay and also direct it to Commerce. No such luck. No efficiencies there.
I am pretty depressed about the state of business lately. AS soon as ebay's additional item specific requirements take effect I'll have to fix those listings that aren't up to par.
