What is PayPal? I always see it as an option when checking out while online shopping
It's a very good payment method.
Once you establish an account with them you can click on the PayPa button of any retailer who uses them, enter your PayPal password, and the payment is complete.
What I like about it is that I don't have to trust my credit card details to every site I buy from. And you don't have to fill out your details for each one.
It is indeed an option you can use to do online shopping and I would say that it's safer because the people who are selling you the products can't see your credit card, debit card, or bank number. It is also a nice way to send and receive money electronically without much of a hassle. I find it useful for making online purchases and transferring money.
