(droplifted) In addition to leaving merchandise in a store, droplifing may also involve coupons that the dropee does not need or want, discreetly left near the item affected by the coupon. It is extremely bad form to leave expired coupons but it's OK to leave coupons that expire the date they are droplifted. This form of droplifting is generally a female activity but not exclusively so.
A very polite and appreciated practice common in the Upper South
i.e. southern Ohio and Indiana, West Virginia and Kentucky. It's more commonly done at stores that offer double coupon redemption such as Kroger and Meijer than stores that don't such as Walmart.
When a store has a super-double coupons
redemption day or week, it is even more practiced.
"I got my deodorant for free at Kroger because it was on sale, they had super-double coupons, plus someone droplifted the right dollar-off coupon on the display!"
"I had more toothpaste coupons than I could use, so I droplifted them before they expired."
