Believe it or not, their official stance on the subject is that there are more risks of the customer being overcharged than trying to sneak with unpaid merchandise. Given the turbo bills people usually pay at Costco - a double scan is easy to miss in the final number.
I love when they pretend to count your 54 items that are shoveled into your cart by their associate in a big heep, then draw a line through the ticket to signify you have 54 items
LOL I find that entertaining too, especially as the line to exit is growing. Regarding testing the batteries, certainly helpful for selling a battery, and stopping people trying to scam them before the warranty is up is just another perk .
Even right here among BITOG members, we have heard people brag about abusing Costco's generous warranty, by returning good batteries, just so they can get a fresh battery under warranty.
Get something double-scanned and Costco will lose way more money dealing with your complaint later, vs catching it right away. There's rarely a scenario where you'll stay quiet on an overcharge-everything at Costco is north of 10 bucks a pop, or almost.
Cannot blame them at all, this should've been in place long time ago. The worst is when they "buy" biggest TV just to return it after Super Bowl or whatever they are watching.
They stopped the no-question tv return years ago. I had bought a Visio(?) tv for my folks that went on the blink after a few years. I went to buy another figuring the warranty was up. The guy looked up the transaction and said, "Bring it in. That one is still under the old program." I told him, "No, that's not right" but he said, "No, bring it in." So I went and got it, and of course got a bigger TV for less $$.
Returned/exchanged one 2 months ago, no test. What if it's not charged. Not likely they will spend the time to charge it and test. More likely they will test the existing battery if you ask.
