From just floating around the marketplace I have sold both multiple DLC packs and games, as well as traded a lot of things between games. I've had over 100 successful trades, but also a lot of horror stories from people that change their mind, claim to have never gotten anything, or try to get me to give them free items saying they'll report me if they don't. After having read the forum rules, I decided to post this; all trades that I undergo with a person will be screenshotted and posted in this thread. Whether it fails, somebody attempts to scam me, or it goes well you will know. This is both to chronicle my attempts at merchanting and to help me find people interested in trading. My stock will always be listed below. Also, to my knowledge, this is not against any of the terms or rules ... if it is, please let me know or feel free to modify/move/delete my thread.

[MapleStory - Broa]: Quite a few hundred million and the following clean gear:
Glowing Whip, White Raccoon Mask, Pumpkin Lantern, Tons of Chairs + More.
[Steam Games]: After having sold quite a bit of stuff my balance is $5. 400ce/1USD.
I can gift people things, as well as trading; so you can 'sell' things as long as I have balance.
[Vindictus - East]: Quite a few hundred million and the following items:
Full Wonderland Set, Black/White/Purple Gnoll Chieftain Hoods.

As for the design and coding, I can do anything from a desktop application to a web application.
You simply come up with the idea and I'll give you a quote and make a working sample of it.
Skinning, random design, and about anything you can think of. I'm best with PHP and C++.
