First, go to the Coupon Database here at http://www.budget101.com/coupons.htm and print out two of the $1.50 off one glade scented oil refill.
Second, don't bother with the $3 trio or 3 refills.


4 Glade candles
2 @ 6.99
2 @ 0.00
2 Glade refill packs @ 2.50 each

6.99 + 6.99 + 2.50 + 2.50 = 18.98 before taxes and coupons

give them your coupons in this order:
$4 off 1 holder
$2 off 1 holder
.50 off refill

$1.50 off refill
BOGO holder (6.99)

18.98 - 4 - 2 - 1.50 - 1.50 - 6.99 = 2.99 oop before taxes

Walgreens currently has a MIR in their EasySaver Guide for the refill packs of $1, limit 2. Send that in and your total out of pcoket is 99 cents!

If you can find more printable BOGO coupons, you can add 2 candles for each coupon and your total will stay the same.
