The best thing you bought in E-bay was...

A copy of guild wars almost 10 years ago. It never showed up though and I was out 60 bucks after selling a bunch of my n64 games :(

When I was a preteen, I bought Doom for the Gameboy Advance. It arrived from "Texas" (Hong Kong) in the "original packaging" (it was a pirated copy) and the saving battery lasted just long enough for me to beat the game once. I wish I still had it, for novelty reasons.

2 Perfectly working Numark Turntables for 25 bucks

Anime

5050 led strip!

$20 Blu Ray / DVD player. I don't need anything fancy, just something to watch Redbox movies on.

A big purple dildo that tastes banana.

Some out of print book worth a few paychecks for less than a meal.

too much too remember all, many vinyls, synthesizers, my best purchase was hand made studio monitors i think

I'm planning on buying my skateboard there, so hopefully it WILL be the best thing I bought there :P

my Japanese pressings of King Crimson's CDs.

A not-really-vintage, german beer stein for $1,50 :D

Huge batch of "as is" arcade PCBs ~$5 each. All but two of them worked and I made serious profit after reselling the duplicate boards.

I grab JK Academy and JK Outcast with box, both for 6 bucks :3

A power port to replace on a laptop would be mine, due to the fact that the laptop was free, aside from that 7$ purchase :D

Well i dont really buy things on ebay that often... but GTA:China Town Wars for the ds, came with the box which had the manuals and the map in it too!, it also came with some stuff from some game convention, i think it might have been E3, it came with a little advertisement poster, like 3 little plastic things filled with a couple rockstar games stickers and gta:ctw stickers, and a plastic bag that says
Grand Theft Auto: China Town Wars on it. i dont remember what else came with it if anything else...

But i Got it for like $7! what do ya think?

A brand new Black and cream Epiphone Les Paul electric guitar and matching hard case. Was part of a container lot headed for Japan but then the Tsunami hit and a company here (Australia) must have bought the lot and they were sold on ebay instead. Even with the postage it was so cheap i paid less than half of what i would have paid if i walked into a guitar store and bought it there. :)
