Rite Aid is running an ad this week offering 300 Plenti points when you swipe your Green Dot card and reload at least $50 in a single transaction. Check your local ad to see if the promotion is running in your area.
300 Plenti points are worth $3 off other items purchased at Rite Aid (and other Plenti partners). In my experience you cannot use Plenti points to pay for reloads. Green Dot reloads cost $4.95.
Note that the ad states “Limit 1 offer per card”. “Card” in this context, I believe, means your Plenti card. It will be interesting to see if this limit is enforced.
