I stopped by HEB this afternoon and these coupons popped up as my reciept was printing at checkout.
They print randomly so be on the lookout for them.
This is my favorite coupon of all 4 that printed together.
If you get this $3 Lunch kit coupon you can piggyback it with the current combo deal at HEB, as pictured below.
They have lunch kits as low as $5 and with this $3 Coupon you can pay as low as $2 for all 5 items.
Super Sweet for Back to School!
