Did I make a mistake or am I okay?

So, on eBay, I bought two items. I didn't create a PayPal account, but because today was my first day buying from eBay I wasn't aware most sellers use paypal. I proceeded to buy the two items, but, I had to choose "Buy using PayPal" option (forgot the name at the moment, didn't really pay attention) and I thought it was completely normal. Am I in trouble for the items not going to ship or the items being refunded because I didn't use paypal or am I okay for now?
I am also using a prepaid gift card (Prepaid visas, you get the point)

You don't need to sign up to use Paypal. Just using your credit card is perfectly fine. All that really means is that your address is not verified, and if something goes wrong with the transaction you have to open a case with Ebay and your card issuer instead of Paypal. The only thing that can really go wrong is if you entered your shipping info incorrectly, but they usually send a receipt to your email that you can check that to be sure.
