I got scammed on a gpu once. It was a too good to be true listing and the seller only had like 1 review and yet I still bought it. Contacted ebay and they refunded me fairly quickly.
Been using ebay more and I like it. Although one of my previous ebay order went through Amazon because the asshole seller just purchased it in amazon and sent it to me. They profited what? $2
Worst thing my company does is supply ESD devices to the MIC. Not exactly sending them armaments but it does kind of help out the MIC.
