your safeast bet, again, you probably shouldn't do anything like this, because once you sell something it turns it from a crime like tearing a tag off a mattress to, a real and possibly jail time type of crime. But if i were to sell something, id do it in a membership site where your not actually selling them but your selling membership to the site, and id also not use them to entice others to buy membership, as that would fall into the same lines as selling them. If i were you id setup a free template site, like i have, templatesite.info and maybe a membership site like i have, members.turnkeysworld.com and on the template site, market the member site. but thats what i would do.
With all the plr and mmr stuff available on this site, why would you bother risking something that hasnt got resale rights?
