Im still pretty new to all this buy/trade/sell websites and such, but i do have a bit of experience!
I bought a Limited Edition vinyl of TOCS on ebay about 2 months ago, and the guy was super nice and I paid on time and the transaction was simple and clean.
I have 100% positive feedback on ebay as well! even though my score is only one, because ive only ever bought one item
Im very cautious when i buy online, because of a horrific transaction that happened about a year ago due to a fake seller.
