$28 for one merit. Are you serious? I don't think so, my friend.
You can earn merit by contributing to the forum through your constructive posts. Getting merits by contribution, don't have to spend money to get them.
I learned the situation about buying Merit, and easily found willing to sell me Merit at a price of $ 28 for 1.
I can afford to buy, but this is against the worthy goal of "Merit". Merit is more than money!
Furthermore, merit exchanging violates forum rules and destroys the original objectives of merit system. And you know what? Sooner or later, you will be found by admin, moderators or by other users in the forum, then your account will be under high-risk of banning (temporary or permanent depends on level of abusement).
Good luck my friend.
