Ralph's and Foodsco B&M has Keebler Club or Town House Crackers 9-13.8 oz for 99¢ with digital coupon clip in the Ralph's/Foodsco ad. There are $2 off 2 boxes coupons attached to the boxes of some Town House Cracker boxes, June 2018 expiration I believe. Pick the coupons off of two boxes. If you can't find the coupon then Coupons.com has a printable $1 off two boxes, which isn't as good but still a good price, imo.
Note that it says that digital and paper coupons cannot be combined on the purchase of a single item. My interpretation is that the coupon is valid because the coupon is being used for the purchase of two items, not a single item. I attached a copy of the coupon, but my apologies I was in a rush and didn't get a chance to take a good shot. It worked for me, and I attached a scan of my receipt.(note that I also bought (2) angel cakes for $2 each which totaled $4, so the (5) boxes of Crackers were $1). But ymmv as always on these as the cashier might refuse to take it.
For those using Foodsco, it is only good Saturday may 26. Ralph's is good today thru Monday 5/28
Also don't just buy 4 boxes as that would be $3.96-$4 coupon, or a credit of 4 ¢, which could cause a problem with the system.
