Clicked "other" as a payment on eBay and now I can't pay!?

[Jenna]

What do I do? I clicked "other," thinking it would lead me to fill in my card details and pay. Instead, it took me straight through to purchasing it. But I don't see how I could have paid. In my Purchase History, it is there but it says unpaid. Something briefly flashed on the screen to say the payment was unfinished. Please help, this is a Christmas present and I need to pay ASAP.
I contacted the seller but he said he'll message if my money goes through. I know I haven't paid though and there are no options to.

Just open a Paypal account with the card you used, it will only take a few minutes plus you will have the advantage any future purchases that you make you wont have to enter your card details. Assuming the seller uses Paypal (I expect he does being a seller) you can then pay him
