There are two Avent Coupons you can stack at Walgreens to get $3.50 off Avent Pacifiers at that store:
$2/1 Avent Bottles, Nipples or Pacifiers Walgreens IVC
$1.50/1 Avent Pacifiers
I checked at my store today and the pacifiers sell for $5.99. But my advice is to print the manufacturer coupon and hang on to it until the pacifiers go on sale. I have a good feeling they might before the Walgreens coupon expires on 9/24.
