charges huge shipping prices may be the explanation right there.If he's purchasing their entire stock to do so and their regular clientele don't get a shot at below market prices, he's an asshole. If he's using his employee status to exceed purchase limits, he's an asshole.
HOWEVER I'm curious if he's legally shipping them without a hazmat contract because UPS won't allow individuals to ship primers without a contract and FedEx requires you to become an approved hazmat shipper with or charges you $115~$117 handling fee per package PLUS shipping costs.
If the store is putting them out at below market prices, and then allowing their employees to flip em at market online, w/o recognizing what's going on, the store is managed by idiots. If there are no purchase limits, and the primers actually go on the shelves at below market price before the employees buy all of em, I'm fine w/ it. If the employees are selling it off the back dock before it ever reaches the retail floor, then yes, the flipper's an asshole. If you walk into any store whose product line you have some expertise in, I don't care if it's primers, batteries, beanie babies, or beef jerky, and you've got $1K cash in your pocket, and there is salable product you know you can move for 2-3X the price on the shelf? You're a poor steward of your money if you don't double or triple your $1K.
The simple fix is for the store to put the primers out on the shelf for the current market rate. You can buy em online & pay shipping & HazMat fees, or you can buy local & save the shipping & fees. Problem solved.
During the .22 drought, a very generous & clever ARFCOMer found a way to ping WalMart's servers to check the stock status of particular SKUs. My brother was complaining he couldn't find .22 LR anywhere. I left his house one evening, and about the 2nd or 3rd Walmart I swung by on my way home had 2x of the Winchester black 1k round packs. They also had a 750 or 800 round pack. They had a 3 box limit. I picked up my 3 boxes, called & asked him if 2800 rounds was enough.
