This is a loaded question.
The gamer will not buy from you he will get your recommendation and then order it online so will the laptop LCD guy. He wants you to spec out the part number. If you do manage to get the sale what do you do when he brings it back and says it doesn't work?
Even if you markup your parts 100% it might not cover all the idiots who will damage the cpu, memory or motherboards and return them for a full refund. Then there are the guys who buy it hold it 30 days and want to return it for a refund. They they lose the receipt and expect you to take additional time looking up their receipts on your computer system. IMO let walmart keep the walmart customers and low margin business.
Then there are the tire kickers who call non stop for the best price. They have no value in their time so they figure you have no value in yours so they call every single number under computers in the phone book and want to price the same part in hopes of saving the last 50 cents. Do you really want this customer even if you get them?
So basically we do not sell parts cash and carry. It is a big sink hole in time and noting comes but heart ache - IMO.
WE build customer computers so we have all the parts we just will not sell them to end users. We cannot compete with bestbuy or walmart so just send them there. An if someone wants to go to NewEgg then why even take their phone call and waste that time pricing it for them.
You cannot be all things to all people. After a few years in business you should figure out who your customers are. In our case they are the people that do not want to be frustrated home techs but people who just want their computers back working correctly.
We do not waste time with very marginal price shoppers in hopes of making 10% on a part sale, mean while your phone is busy when a high quality customer has a broke computer and needs you to come out and fix it so he calls your competitor whose phone line is open at the moment. All our time and energies are reserved for the customers who we make our living on. Break fix and networking or consulting. Someone might some day get a busy signal calling our phones but it will be because we are already helping another quality customer not because we are let some tire kickers waste our time on the phone.
Next time they call just say "Of course we have parts to fix our customers computers but we do not sell retail parts, have you tried Bestbuy?"
How do you guys deal with people who call wanting to buy computer parts from you but plan on installing it themselves. Had several people calling in the last few days. One guy was a gamer wanting a 550w power supply and another one wanted me to order a screen for his laptop :-(
As I see it I can either:
1: Sell parts to the do it yourselfers and just be happy from the small amount of profit from the markup.
2: Not sell parts at all to customers unless I install them
No way I was going to order the laptop screen, but if I could make $25 in 5 minutes selling a power supply I have sitting on the shelf it's somewhat tempting. On the other hand what if they want to return it later or something. I just have a small shop build into my home so I am not a retail place by any means. So what say you guys, worth the money or not?
