From what I know, they stock and ship nothing.
They approached the dealership I worked at and wanted us to come on as a "vendor". In short you buy something from them, they contact us, we order part then ship to their customer. They pay on 30 day cycles. We get to do all this at a reduced profit margin and a set shipping rate. So, if we get $7.00 to ship a part and it costs $10.00, we eat it. They also expected me to sell them a part at 5% to 7% over cost.
The markup on Mopar Performance and Mopar Accessories might be 5%, 12% if you're lucky, so there's no wiggle room there. Their argument was 5% of something was better than 100% of nothing. It's not when I figured in the shipping material, the man hours to deal with the orders, the hassles of returns, chasing down payable's, and credits, it was a loser deal on my end and a great deal for them. All they had to do was maintain a website and (hopefully) write a check.
I passed on their offer, but I see there are others who didn't. Those are big dealers who are making the difference up on the backside with purchase discounts. I'm of the opinion that I was going to get those purchase discounts anyway, no need to ***** my self out for it.
