Target has a Fiber One promotion going on right now where if you buy 5 products you get a $5 Target gift card. Here is one idea for how to work this promotion:
Buy 2 Fiber One Yogurts $4.08
Buy 2 Fiber One Cereals $5
Buy 1 Fiber One Bars $2.50
Use 2 $1 Fiber One Yogurts
Use 2 $.75 Fiber One Cereals
Use 1 $.40 Fiber One Bars
Pay $7.68, Get $5 Target gift card
Final Price: $2.68 for 5 items! ($.54 each!)
There are other ways to work this promotion with all of the new coupons available, so do a few separate transactions and get a bunch of cheap Fiber One!
