cashiers = 2 something per 1000 rung up.
customer service supervisors = based on the coverage of the cashiers. some cashiers make more than the supervisors.
loss prevention = set amount per incorrectly rung up transaction (people checking your receipts.)
EVERYONE = set amount per mismarked item (i.e. wrong price sticker on an item)
sales associates = commission based on the actual item itself. if sold below cost, no way does it have commission. most sale items = no commission. big money commissions = audio/tv/appliances and components. that's why they push the warranties, because they get a good chunk of that.
managers = based on the department performance.
