Buy two tubes of $3 Crest toothpaste.  Clip the $3/2; subtotal will be $3 plus tax and you’ll earn a $3 Register Rewards.  Pay with Wags Rewards and only shell out for high tax – I shelled out 42¢.  If you prefer another variety, you might end up spending more – – the $3 tubes are the cheapest varieties included in the deal.

Note I did not get the RR (I was actually looking for Cash Rewards, based on the checkout info) and have given up on trying to explain these things to the constant manager turnover.  While they’re always super nice about it, it’s too long to spend each time explaining what a RR is, the digital coupons and paying with Rewards.  I just called customer service and $3 was put into my account immediately.
