In the BC Flyer you can buy a book of Canadian Stamps at the cash register (usually, not postal office) & get 10% off, limit of 2 books. Will be doing 5 or 10 trips on this one as we send out a lot of mail & it's great to use on the parcels that we send out at Christmas. Also, there is no value on these postage stamps so there's no expiry date & you can save even more money when the price of stamps go up next year. Also, combine that with the SDM $150. gift card promo to get the 8,000 pts that's ending on Friday, Nov 16th & take advantage of both deals. Note YMMV & also you may have an issue with some cashiers & stores that may not allow you to use the SDM GC to buy the stamps.
