How many payment gateways

If you've never set up an e-commerce store, it might be confusing how many payment gateways you need. In short, you only need one payment gateway. However, it's possible for that payment gateway to go down, or more likely for a credit card to be declined, in which case, it's a great idea to have a backup payment gateway such as PayPal.

If you have the time, set up both payment gateways. If you only have time to set up one payment gateway, I'm a huge fan of Stripe since it's very easy to use and test without having to enter a bunch of information for a test account.
