How to pay online without a credit card?

There are pre-pay debit cards from AmEx, VISA, and MasterCard in most supermarkets, pharmacies, and other places. You put money on those. The downside are the monthly, per-transaction, and reload fees.

EDIT to add: There are also Gift Cards for iTunes, Google Play, Barnes & Noble, Sony, and many others that sell online. That's another way to pay. The downside is having a balance too small to spend on anything without getting another card.

PayPal connected to a bank account.

Paypall.

Question where do you get dummie credit card info? I used to be able to watch movies online free but now there always are asking for credit info to sign up to watch a free movie. So any answers?

In the UK you can use GoCardless. They can set up a direct debit instruction for a bank account.

Paypal or Bitcoin - though only a small number of businesses accept Bitcoin as payment.
