Holiday Shopping Online
It’s December. In general it may take up to three and half weeks for a parcel to come from a store in the U.S or the U.K. And that is compounded by the mail service being overworked with everyone sending parcels (unless you pay the extra fees for priority shipping which can be outrageous). If you want to give the gift of a shopping experience for your plus size lovely/friend/partner/spouse/sister/mother then gift certificates are a safe way to go. They allow the shopper to shop at their convenience for what they want (instead of what you think they want or need). And they arrive safely to their email. 
There are lots of online shops that offer gift certificates (e-certificates, gift cards) online that ship to Canadian shoppers. Here are a few in no specific order that I checked who offer gift certificates: Torrid, Addition-Elle, Penningtons, MXM, Hips and Curves, eShakti, Her Room, Forever 21 Canada, and Toni Plus.
You can find these stores and links to their shops listed in the Canadian stores and Canadian delivery listings. If you can’t find an obvious banner for gift cards try looking under the website’s “customer service” text link; most likely near the bottom on the front page.
Happy gift card shopping!
