Question about a tapjoy offer

Aloha,

This offer is on my offer wall. Has anyone here done it yet? I was wondering: what is a mco and what does it cost? Do I have to purchase more than that mco to qualify?

Thanks for any helpful replies.

Mco is a debit visa card so you Can shop for your bitcoins
So you have to buy that card

Thanks. Has anyone actually completed it though?
