Isn't it ridiculous how much paper retail stores are wasting on register receipts these days?

I think the average minimal receipt at Walmart is 10–12” minimum.

The worse offender I know of is Kmart, where you get a substantial receipt for your purchase (maybe 7–8”) and a minimum of 3 in-store coupons (probably 5” each). And I bought, like, a bag of chips.
