Storage Space?

Yes, storage space. Where do you plan on storing all your ebay inventory? If you only intend on maintaining an inventory of 50 - 100 items at all times, it probably isn't too much of an issue. That's how I started. Then, I grew in to a one-man operation holding 2 - 3000 separate items in ebay inventory.

I started out by building a couple simple wooden racks out of ordinary 2x4's and plywood in one of my spare bedrooms. When I out-bought that storage space, I began renting those off-site storage rooms. At first I rented a 12 x 12 and paid monthly. Then I outgrew that. I currently rent a fairly large 20 x 40 unit, and pay annually. I know most people won't be able to pay annually, but in doing so I was able to shave off 35% off if I had paid month-to-month. 

My #1 rule is take care of the customer, and #2 is take care of the bottom line. Saving 35% is almost like getting a 35% raise, of sorts. When was the last time you received a 35% raise?

Most reputable storage facilities are secured and protected with surveillance cameras, so it wasn't a big concern for me to use the ones I did. Besides, someone had better be pretty hard up to break in to a storage unit which is likely contained with such low-valued items as old bed mattresses and bags of clothes. Not too much of anything valuable is at most of the storage facilities I've been through. I never had an issue at any of my sites.
