I don't know about cosco's return policy, but lets look at lowes, and home depot. both have 90 no questions asked return policies, on most things, there are some items that have a 30 return limit. it does not say unused, unopened, or any other limitations, gas power items have to have the tank drained, power tools need to have all packageing, and parts, other than that return at will. as someone already pointed out, these two giants still have the lowest prices around, and will match their competors prices plus 10% if you find it lower. so where is there a price increase passed onto the consumer?
so if i take advantage of their pricing policy by finding something cheaper somewhere else, and asking them to match it plus the 10% does this mean I'm stealing as well???
I've talked with managers, not 18 year old store stockers, at the stores i deal with, and they have no problem with anyone using the policy, . they see it this way they will refund the money on 100 items, and book the sales of 10,000 items. even the returners spend money on the wood, drywall doors, shingles and such.
