You will be hard pressed to find anyone (with any sense) selling altcoins for a Paypal or credit card payment..
Get some BTC first...
but if i setup an escrow deal I make the payment before I receive anything. Once I receive the coins they release the funds to a direct form of payment.
If someone really want's BTC, i can make a BTC -> MRY trasaction.
I am not opposed to it at all.
