I get that you were talking about FBA... I was just ranting a bit about middleman sellers in general I guess. You didn't need to do a point by point explanation of why it doesn't apply to FBA, especially after you surmised I wasn't talking about FBA. ;] I'm well aware about the dangers of relying on Amazon sales. Sadly in the used book world it's almost impossible to break free of it. The store does list on many different online marketplaces, but no matter how diversified, the majority of the sales come from Amazon. To answer your questions... 1. I'm not sure if it's be beneficial to cancel the order if it were repercussion-free (which it most certainly isn't and never will be). I haven't done an analysis of money made versus time wasted yet, since Amazon will never make it repercussion-free. I have a feeling that even if it's still _technically_ financially worth it to not cancel the middleman orders, it'd be very close to being not worth it. 2. Middlemen are usually _very_ easy to spot due to their ordering habits and addressing habits, at least if they've ordered from us more than once. It's possible that some of the only-ordered-once people are middlemen as well, but last I looked, only a small percentage of them were likely to be (based on shipping names not matching Amazon names). I haven't really looked into middlemen sellers in FBA, since they never really bothered me much. Plus most of the stock that we send for FBA are things that don't move in store, and we've kind of given up on and are just trying to get a little bit of profit on. So we generally don't care about the FBA stock (beyond ensuring that any lingering stock is "disposed" before the 6/12 month fees hit if it's not selling).
