Deal scenario:
Buy 2 Nivea Touch of Happiness Body Wash on sale for B1G1 FREE at $5.99 each
Use the Buy 1 Get 1 FREE coupon from the June issue of All You mag
FINAL COST: 2 for FREE!
Heres how it works: Walgreens pays for the first FREE one during their B1G1 FREE sale and the manufacture pays for the second one you buy, since you are suppose to get a free product when you use a B1G1 FREE coupon anyways. Get it?
All You magazine, which is filled with tons of valuable coupons, can be purchase at Walmart for around $2-3.
