I have purchased 3 items at an online audio site and recently made my first sale. Not having feedback makes one hesitate and it takes time to get established, particularly if one does not buy/sell alot of items.
Next I will be selling my larger integrated and asking over a grand. It will be relatively low priced compared with others but still its a chunk that could attract scammers, low ballers, etc.
I sell media on the A/zon platform and usually have had good experiences with an occasional blip: refunds/returns/undeliverables but there have been a few scams. I learned my lesson and will not ship to certain individuals, just cancel the order.
Hasn't affected my feedback which indicates they intentionally scammed me. A few times someone returns a different item than the one received, financially it wasn't worth the trouble but I do report them to A.
The world we live in.
