I think the best way to sell TCredits would be to advertise the great deals one can get when bidding in PriceBenders. It is very exciting to see how inexpensive items can be purchased and TCredits are needed to bid on them.
If you are wanting to advertise for free, advertise in locations where Auction's are, because typically people at those sites are interested in Auctions like PriceBenders. If you can, post on your facebook about it, and friends and family could join in as well!
