[Buying] (Paying someone with a linked credit card to paypal)

I'm paying someone to buy something for me.
I'd like to buy a $30 1 year membership on a forum. But cannot do so unless I have a credit card linked to my account, which I don't have. So I'm paying anyone with the requirements $35, as a gift (I will pay the fees), after they have bought me the membership.

I will go first if you're a trusted member. Even though not going first would sound rediculous to most people but I'd rather not risk losing $35.

Thanks!
