ive got a store that always has a ton of random doors that are either online or custom-order returns. they have those 'dept sku' yella tags. not sure why yall are debating ymmv stuff like its consistent...
fwiw, bought some batteries instore via online, put my inconspicuous proof mark on em, returned em later opened unused and proofed... found em on a shelf months later with a half off dept sku yella tag and talked the chick into $50 off the 'opened junk'. i didnt plan it that way but a win is a win
ymmv
