Walgreens myBalance Rewards do not usually allow users to buy alcoholw unless otherwise stated. Since myBalance reward accumulation depends on your final purchase price, you may be inclined to think that you may be able to use it on any item you’d like. However, some restricted items such as alcohol and cigarettes are generally restricted for all myRewards redemptions. Some exceptions apply, so you may be able to use your Walgreens myRewards coupons to buy alcohol under certain circumstances.
