A few more tips for selling on Ebay:
-Buy a decent digital camera. They can be had fairly cheap these days - less than $100 in some cases. It doesn't have to be a top of the line camera with all the bells and whistles - but it needs to take decent pictures. Kodak and HP both make great, inexpensive cameras. (I have an HP myself and love it.)
-Buy a mannequin if you are going to sell clothes. Am I kidding? A mannequin?? Nope, not kidding. Go on Ebay and search on "mannequin" or "hang up mannequin". There are sellers who sell male and female versions of an armless torso (in both black and white plastic) which is merely a shell of a torso, with a hollowed out back and a metal hanger (like a clothes hanger hook) on the top. These things are fantastic for photographing clothing to list on Ebay, and they look so much more professional than just laying the clothes out on the floor, sofa, etc. I think I paid about $15 each for mine (bought one black and one white) a few years ago. Now that I have them, I'd never do it any other way.
-Buy a decent scale for shipping. Ebay has tons of scales listed - digital postage scales go for anywhere from $5 to $60, and vary in capacity, features, etc. If you're going to be shipping items yourself, you'll need to weigh them carefully and be sure you charge only exact shipping costs - or your bidders will be sure to let you know about it in their feedback. On the other hand, undercharge for shipping, and you're shooting yourself in the foot. Don't guess - get a scale!
-Find a niche if you can. Ebay has pretty much everything under the sun - but if you can find something that is unique to your area, or something that doesn't appear very often on Ebay and seems to be in demand, you've got it made!
-Consider selling for other people. Ask friends, neighbors, co-workers if they have items they'd like to list. Many people want to sell items they have on Ebay, but they don't want to mess with learning how or don't have time. They'll probably be happy to give you a cut of the sale to get it sold. However, a word of warning: make sure the agreement is clear and in writing between the two of you - if you list the item on Ebay, they can't sell it to someone else in the meantime, and it has to be available to you to ship or arrange pickup by the winning bidder. Also, be careful of high-dollar items...if you are listing a high-dollar item for someone (like a car or valuable antique item!), it would be best to leave it in their possession until it sells. Don't bring it to your home, to avoid any problems - in the event of a break-in, fire or damage to the item, your homeowner's insurance would not cover the item, because it was not yours - unless you carry business bailee insurance!
-Read Ebay & Paypal's new policies! Things have changed drastically in the past few months, and to my knowledge, Ebay is not backing down on the new policies, regardless of the recent seller "strike" and general discontent in the seller community with the changes made. Sellers can no longer leave negative feedback for bidders as of May 1st (I think that's the date) - so if someone buys from you and doesn't pay, or pays late, you can't leave negative feedback - but the bidder can leave a negative for you. Also, Paypal now has a policy in place that all new sellers' funds from Ebay sales will be held for up to 21 days - meaning funds for the sale of the item AND the shipping money. (There are also other reasons for them holding funds, but that's the biggie.)
Just thought I'd throw a few more tips out there for those interested in selling on Ebay. I'm not trying to make it sound difficult - it's really not - but you have to know what you're getting into and what to watch out for!
