If that was meant for me and not Fluffy:
Industrial cleaning equipment, the kind you might use as a part of the manufacturing process, printed circuit board mfg & inspection equipment, forensic equipment (think CSI), some small consumer electronics.
Sites are set up for specific markets, and promoted accordingly. Interestingly, some of the nicest orders come from the sites with the least traffic. Typical ticket is $100 - $2500. Minimum order is 25.00, largest ever received straight off of the net was 26,500. Yeah, had to read that email a couple times
Largest # of orders is for consumer items, so lots of small tickets.
2005 sales just over 1,000,018.00 on the net plus another 28k in commissions. This translates into low six figures, plus free car and 100% medical, dental, optical.
Nice perk: As a corporation, we have a policy that all employees get a health benefit to promote wellness. This covers wife's gym membership, chiropractic, supplements, Lifecycle, whatever else I can think of. Only rule, if you do it for one employee, you have to do it for all. Nothing like buying your supps with those pre-tax dollars. Also paid for "company gym" with power rack, etc etc.
Just me and my sweetie helps out a few hours per month.
Single largest customer: US Gov't - Although a lot of times, you can't tell who is really ordering something. No matter, it's all to get the bad guys.
We take all the major cards, PayPal, purchase orders, checks, echecks, money orders, and if someone offered me a chicken in barter, I might consider that as well.
First site designed by my oldest when he was 15. Incredibly, it made money from day one. Now up to 7 with two more coming on line in late spring.
If anyone reading this is thinking about an internet business, go for it. Beats having a job!
Just don't fall for the pitches you see on TV. Start small. Make it pay for itself from day one, and don't quit your day job.
