With this current promotion, after you spend get 100 points on select items from now until 2/7/17, you can get a $50 gift card (or a combination totaling $50) from any of the gift cards they sell in store, which is a lot! And from what I can read in the terms, this is every 100 spent in that time period, not just a one time thing. The list of participating items is very large, you can see them all here, and includes large name brands such as Aquafina, 7up, Gatorade, Tostitos, Betty Crocker, Red Bull, Quaker, Oreo, Tide, Pepsi, Nabisco, Dannon, Freschetta, Dr Pepper, Progresso, and Red Baron to name a few.
So go do your shopping and start earning those gift cards! You do need to be signed up for their rewards and add this reward to your account to qualify. You can see all the details explained here.
