Alright well I will warn you now I just read about someone that purchased 76 of these in a row at one store. So I have a feeling a lot of stores will be totally wiped up so keep that in mind before you rush out.
There is a nice deal at Walgreens though and as of posting this is still working but it could end at any time!
Buy 1 Gatorade 20oz at $1.70
And hopefully you get a coupon for a free Gatorade Prime AND a coupon for a free Gatorade Recover
Then you go get those 2 items and you should see another set of free coupons print. So in theory you can just keep doing this over and over. I do think it is going to bring you good coupon karma if you set a limit on yourself and leave some for others.
Here is one other thing- this is working for a lot of people all over the place and not for others all over the place. So you can head in if you want to give it a whirl and see how it goes for you. Make sure you check the expiration dates and make sure you grab that 20oz size not the 32oz size for your initial purchase.
