Well at Walgreens brand dental floss is cheap this month at Walgreens! A 50-yard package of dental tape is regularly priced at $1.99 for one, or $1.50 each, when you buy at least two. Use a Walgreens coupon from page 14 of the April Savings coupon booklet from the front of the store by the weekly ads. The Walgreens registers will automatically deduct the $1.00 coupon for every corresponding floss purchased. Buy two and pay $0.50 per floss!
