Ive been buying off ebay for about 10 years probably and until this year never a problem.
The problem, partly my fault, I never looked at the feedback of the seller. was the item never turned up. I waited the compulsory time and then reported to ebay. Ebay refunded me within minutes!! and the seller I guess was banned as he/she disappeared from ebay!
I found it good for the first 5 or so years (joined in 2001), when it more like early carboot sales. Genuine people selling unwanted items, making a bit of pocket money. Then, like bootys, the traders and individuals looking to buy and they sell at profit became prevalent, and it all turned to shite.
So much is Hong Kong tat, even if you specify UK location, and all of a sudden they don't speak English when something goes wrong, or insist you post it back to Hong Kong at your expense. Even UK sellers are just selling tat or unreliable stuff. Its not particularly cheap (due to traders), and its always hassle I don't have time for.
Trouble is, I've always been a sucker for mail order... ...the excitement of deliberating and choosing something, and the anticipation and excitement of waiting for it to arrive...
...then the hassle starts, trapsing off to the sorting office (with no parking) to pick it up, finding it doesn't work properly, off to shops to buy packaging, off to the postoffice (with no parking) to post it back.
