More and more gift cards are now redeemable online. Whether you purchase an electronic card or a physical card, you can often input the card number when purchasing an item on the retailer's website.
Using a gift card online also means that you're no longer limited to the geographic area in which the retailer has stores. Just make sure that the retailer ships to your location before purchasing the card!
The exact procedure for using the gift cards depends on the specific website of each retailer, but usually during the payment process, when you are at the checkout stage, you will have an option to enter the gift card number.
Here are all the retailers that allow you to redeem their gift cards online:
La Vie en Rose / Bikini Village
Indigo / Chapters
Grocery Gateway by Longo's
The Chopped Leaf
The Children's Place
