Champ, I'm sure they're reputable enough that they'd refund your money for this "inexcusable offense". After reading your post #24, let's just cut the chase: Sure, you'll simply have to take your business somewhere else. To you, this is intolerable.
We all know Kellyco is sort of the "Kmart" of metal detectors. As opposed to being the "Macys" of metal detecting. And there is nothing wrong with either business model. If you want the bargain deals, you go to Kmart. Sure their not glamorous. The bathrooms will be un-tidy. The cash register lines long and noisy. Stains on the floor of mis-matched tiles, etc... Or you can go to Macys and buy the same exact pair of Levi jeans for $8 more. But the bathrooms are spotless. The employees more dapper. The service more lickety-split, etc..... Yet in each case, you got the same exact pair of jeans.
You just have to have a bit of patience when you're going to the 'big box' dealer for a bargain. If you don't (and I'm not justifying their "egregious offense"), then sure: You'll need to take your business elsewhere.
