Walgreens has both Glade Decor Scents Refills and Plugins Warmers on sale 3/$3 through 4/26. You will have to buy at least three of the same item per transaction, so you won’t be able to mix and match. Here is what you can do:
Buy 4 Glade Decor Scents Refill Singles $1 each when you buy 3 ($4)
Use $2/2 Glade Products coupon
Final Price: 4 Free!
Buy 4 Glade Plugins Warmers $1 each when you buy 3 ($4)
Use $2/2 Glade Products coupon
Final Price: 4 Free!
Just to clarify, you must buy three to get the $1 price on each, but you do not have to buy in multiples of three. That is why the fourth will still be sold for $1 in each transaction. Enjoy!
