Games must be in English, US compatable versions. Let me know prior to the trade if your game is missing manuals or is an OEM(part of a bundled software package). It may/may not affect the trade but not letting me know before I ship is dishonest and will be reported as such. Don't send a copy/cd-r/back-up of a game, originals only. If you have trouble shipping when you say you're going to, please trade with somebody else. Don't send a defective or unreadably scratched cd.
I've gotten rid of most my boxes. They are a useless waste of space, unnessessarily large too. A couple of my newer games still have boxes, if it does I'll include it, most of the older ones I've thrown away however.
I like trades only, unless the amount of cash you were going to offer is too good to be true and would make a grown man cry tears of joy at his new found wealth, in which case you'd have to ship first.
