Nope, unless its 12 or more....... I had a cashier decide to cheat a little with scanning. If the customer has 10 of the same items(same UPC), 12quantity and then voided the 2 items.
There are a few items where it is possible to do a quantiy price override. It'll be the few items that you can quantity scan.
Last time I checked Kroger 24 and 32 pack waters are able to be quantitied even if it's only 2 or 3. This might vary per store, district, or division and it could have changed since the last time I've tried to quantity water.
