Oh, I should add that I was visiting friends in Toronto and went to a Shoppers (I believe it was in Ajax), that had an actual boutique in it! Designer purses and watches - I would definitely redeem for that if they had one in my area!
Also, along the lines of what ticul said, I also redeem for Christmas gifts. With the Shoppers pre-order forms for games last year, I was able to get my brother 2 xbox 360 games, a tablet for my dad, and a Sony ereader for my sister-in-law (along with a few other items at 2x mega redemptions).
