I am such a huge fan of Terra Vegetable Chips, but they always tend to be very expensive and there are hardly ever any coupons for them. Right now we have a very nice $1 off coupon for them and it makes for a pretty decent deal at King Soopers and Kroger stores right now:
Terra Mediterranean or Original Chips $3.49
-$1 Terra Chips Coupon (direct link)
Also, if you are wondering which type to get, I really like the Mediterranean.
