Every now and then, Safeway has their 12 pack Coke products buy 2 get 3 free. That's the sale that we wait for.
MyCokeRewards.com currently has BOGO coupons for 12 packs for 200 points. You cash out your points, it sends you to a bricks link, you print your coupon. Yes, that's right, a bricks.com link - the ones where you can hit the backspace and print it a second time. I've done this deal 3 times today - so spent 600 points and have 6 coupons.
Here's my scenario:
Get 3 from Safeway
use 2 BOGO coupons to get two more free...
and those two count as being purchased... so I get 3 more free from Safeway!
So for the cost of 2 12-packs, we'll leave with 10 of them! Repeat this 3 times that week and be stocked up with Coke for about 2.5-3 months or more for the price of 6!
How do you get the points? Inside the box of Coke - where you tear open the fridge packs - there's a code that you can type in to mycokerewards.com. Enter your codes and keep building your points value. I also get extra codes by checking the box bins at Safeway when I go to return my cans. Many people just throw them out - I usually leave with at least 3 codes (30 points) - I once came home with over 100 points!
