If you look at the payment screen of the ordering of your ProJumps the menu states:
Credit / Debit Card > Mastercard, Visa, Delta, Switch, Other
By Phone
Postal Order
Registered Cash
I dont think Paypal, at present, is an option. Although it would be a good move cos its just so easy to do stuff by Paypal - but hey, I'm not the sales team!
Hope this helps
