I've recently gained experience in digital advertising, as I've created several online-only flyer pages and e-mail blasts, for Giant Tiger. I've also some experience in building Twitter page banners for clients. Here are some examples.
I have built two Twitter page banners for clients, including The Ballpark Guide, and the Steve Warne Project podcast.
The Giant Tiger flyer will occasionally have online-only extra sections called Online pages. I lay these out to look similar to the flyer, but unique as the items are not featured in the print flyer. Here's a slide show of several examples.
Four times a week, Giant Tiger sends out emails featuring items that are featured in the flyer, as well as special online-only items. I create the layout for these emails.
