Unfortunately the tracking provides limited insurance anyway. You end up paying more for the tracking and then the buyer simply changes it from "not received" to "not as described". Even if they mail it back, even with tracking (usually at your expense again), the envelope is empty and the buyer has a delivery receipt.
1. The item
2. The shipping and tracking
3. Possibly the return shipping
4. Oh and maybe even negative feedback still!
I still use eBay
to unload my excess stuff but I assume a loss of some stuff. It's sure annoying, though. One time, I sold some higher end Russian stamps to a huge buyer. He claimed not as described. Same situation above. Low and behold, he listed them on another account months later with the identification I used. Thankfully I'm horrifically vengeful and kept a vigilant eye plus took significant time to track his purchases and resells and got eBay
involved. Even still, they never did ban him - only took away the negative feedback HE left me. It's sad they don't protect sellers, especially ones with remarkable selling records. What is the point of the feedback system then??
