Save big on Allegra Allergy at Rite Aid! The 24-count boxes are on sale for $12.99. Plus, buy one and receive 100 Plenti Points. The Points are worth $1.00 which can be redeemed on a future purchase. Use a $5.00/1 Red Plum newspaper coupon. Later, submit for a $5.00 MobiSave offer and a $4.00 MobiSave offer. I tested the rebate offers and I was reimbursed for both! After the sale, coupon, Points, and two MobiSave offers, this purchase is a $2.01 moneymaker!
