Technically, if all things go well, one could have $80
1. $10 exclusive ebates+ shop.ca promo （这个找不到，请给链接）
2. $5 ebates.ca sign up bonus （这个有）
3. $15, save 15 coupon code （SAVE15 不好用)
4. $25, shop.ca promo sign up(这个有）
5. $25, paypal + shop.ca promo（这个据说只有特定用户有。还没付款，不能确认）
-- $80
6. 20% cashback from Ebate.ca. (depending on your area) Personally, I should be getting around $40 on ebates.ca --> making this very hot （这个有）
