Many people don't go through the hassle of reselling.
I worked as a dept manager at Lowes for 7-1/2 years
Here's what happens
Original price was $100 for a door handset with deadbolt
find on clearance (say 50% off) Now $50
Then ask for an additional discount (MOD goes an additional 50%) Now $25
(some Lowes likes to blow out the clearance to make room for new stuff)
Customer buys last 4 on shelf total $100 ($108 with tax)for $400 worth of product
Once the last quantity is sold item goes to zero on hand.
Then after about a week or so (in most cases) price jumps back up to $66
Or better yet, Lowes across town has not dropped price yet, so customer drives to other Lowes, returns product for $100 ea.
That's $436 in store credit
So now after $108 investment they can buy a $400 gas grill which is really what they wanted to begin with
Never have figured out why they allow it.
Also When they have buy xxxx get xxxxx free
Current example
Buy Kreg jig kit for $129 and get $20 box of screws free
Instead of ringing up $109 for jig and $20 screws (still $129) they charge full price for 1 then 2nd one is free.
Then they return the jig and get initial investment back, and then return screws and get $20 on a gift card. (Most, but not all the cashiers are clueless)
So with a bit of work (hey thy are at Lowes any way) they can get things they want for free.
But the reality is that Lowes needs to be profitable
So those who are honest pay higher prices on the stuff they buy to cover the loss.


And the amount of shrink/theft is mind boggling
Some stores are $150k-$250k in shrink/theft per year, per store
