It could happen, but I don't think I've ever found an OEM that listed parts for less than you could get it from a reseller. It's possible. I'd have to find the p/n I bought and compare. It would be good to know one manuf is out there that is competitive.
Certain manufacturers in the marine market do not have "retail" pricing or "wholesale" pricing. Everyone gets the same price. I can think of a number of them and as a marine installer I avoid them whenever I can. Even when I try to make a measly 10% margin, in a weak attempt to cover my time spent researching, ordering it, delivering it, experience in choosing and sourcing quality products, installing it and then standing behind it, an owner undoubtedly says "
Jeez I can get that for 10% less."...
These days when a company does not offer even a 10% discount to the trade, and numerous marine companies do not, I tell the owner to supply the part and they get to warranty it too. I am also doing this with brands that have low reliability when an owner insists on me installing that product against my advice not to. I currently have two electronic equipment companies on my black list and soon to be three.
What this all boils down to is this means that anyone who wants to sell that product has to mark it up beyond the manufacturers
single price in order to make it worth while selling, handling and standing behind the product.
Last fall I had to tell a customer, who insisted he supply parts, (I was 11% higher than the lowest priced
legitimate Victron dealer) that his dead "Victron" MPPT controller was not a Victron at all but rather a very poor Chinese counterfeit copy of a Victron. Course he was beyond his 30 eBay period so he could not even give the seller a bad rating.... D'oh...
On Tuesday a customer called and wanted to buy Westerbeke parts from me. I simply told him to purchase through a Westerbeke dealer as my discount is roughly 10%. I was not interested in ordering, delivering and then standing behind the parts he needed for that kind of margin, it's simply not worth it. I will be installing the parts but any warranty issues he deals with Westerbeke, not me. I was brutally honest about it and he was fine with it... Considering Westerbeke is putting a 300 - 700% markup on many items it's pretty ridiculous that my trade discount is about 10%.
Heck I recently sourced a solenoid Westerbeke "re-packages" and got it for just $24.23. They sell it to me with my trade discount for $238.00.... I sold it to the customer for $31.49 (my cost X 1.3) and he still saved well over $200.00. I could have actually made more money reselling the more expensive Westerbeke part at a 10% mark up but I chose instead to save him some money. I did not charge him for the time spent crossing it over which was about 20-30 minutes. Even with a cost X 1.3 mark up I still did not make any money on that part when you account for my
hourly rate spent researching and saving him money.
