The explanation is simple, mbbg buys gear Japanese people want to sell, not buy. While I, the MF Scarecrow, buy gear Japanese people don't want to sell but many want to buy.
It's called auto extention and it will drive you mad.
Basically, if someone outbids you towards the end, it's extended by 7 or 8 minutes. On and On. Meaning the ad could be at the top of the page for ages, attracting more buyers...
Sunday it auto extended 5 times. There I was like an idiot thinking I was golden at 20k and 2 seconds left...nope. 5 auto extensions and one hour later later it was 41k. So I gave up and decided to buy a stinger instead.
Big mistake! The same thing happened all over again, leaving me in a foul mood. Hate it.
