There are a number of payment options, with American Express being one of the largest besides Visa and Mastercard.
Unlike the main two, American Express issues its own credit cards (while also operating a payment network), although Scotiabank does offer some co-branded cards too.
Unlike credit cards, American Express also offers charge cards that have no pre-set spending limit — but that doesn’t mean you can spend as much as you want.
Debit is another alternative, especially where credit cards aren’t accepted. Money is taken directly out of your account and you won’t have to worry about paying a bill later.
PayPal, which offers purchase protection, is a different payment option that some online retailers accept. However, neither debit nor PayPal have the perks that credit cards do.
