“Peelie” is coupon lingo for peel-off-style-coupons typically found on packages or products at the grocery store. Shoppers (like you and I) can peel off peelies and file them in our coupon box for future use. (Or maybe you’d like to use it right away!)
For example, I bought these Chi-Chi’s tortillas and there was a “peelie” for 55¢ off a Real California Cheese product.
Oh guess what? Underneath the peelie there was another surprise waiting for me!
