Amazon Local has a free deal of the day today: get a voucher for $10 off a purchase of $20 or more at Rite Aid Online! The voucher is only valid for online purchases at Rite Aid; it is not valid in-store. I haven’t checked out Rite Aid online so I don’t know what their prices are like, but the great news is that the voucher is completely free, so there’s not much to lose.
Go here to read more and get your voucher. You must input a credit card to get the voucher, but the total is $0.00.
