Here’s a great deal at Fry’s. I found Sheila’s Brownie Brittle for $3.19 on sale from $3.49. You can score a coupon on Hopster for $1/2 Sheila G’s Brownie Brittle.
Or, boost the offer to $1.50/2 for 500 points (by doing a few activities). The boosted coupon will score you the Brittle for $2.44 per bag (Reg. $3.49).
My store had it on the end of the Paper Aisle, if I had to tell you exactly where it should be I would best guess the Natural/Organic area.
