Tina, everyone has their own way of determining listing prices. Some will list at $0.01 or $0.99 to watch the action (not a bad idea on free listing days--just to try it). My philosophy is more realistic.
Listing price = minimum price acceptable for item + all listing related fees (photos, scheduled auction, Buy It Now, etc.) + estimated FVF & PayPal fees. You may want to include estimated (or actual) cost of shipping supplies (I include mine in my shipping charge).
Personally, I never list an item for less than I am willing to sell it, so most of my items rarely have more than 2 or 3 bids. My listing price usually is set a bit higher than I would expect to receive at a garage sale, but somewhat less than I can claim as a tax deduction for a donation. I also check the the completed auctions on eBay for similar items (I'm selling stuff from around the house, so "similar" can be a stretch at times!).
The other thing I do is look at my listing price + shipping charges (be sure to add shipping supplies) to determine if it's reasonable. Would I purchase that item for that price? Is it a good value? Sometimes the answer is no, and it goes into the contributions, garage sale or consignment shop boxes instead of eBay. Other times I'll take a chance and list the item anyway. Sometimes things I don't think are a good value sell for more than my listing price. Other times, things I consider a steal languish and never sell! Go figure!
Another thing to consider is grouping similar items into lots. It's much more convenient for you, and can be a very good value for buyers. If you have four garments in the same size range, it might be worth listing them as a lot, rather than individually. It depends on the items (very dressy or formal may not work well with very casual!). You get the idea!
It's all a matter of personal preference and trial and error, with a lot of research thrown in for good measure.
It isn't a fast way to make a lot of money, but if you're willing to do your homework and invest a little time, you can make some extra money selling things that no longer fit in your life and are more appropriate to another person's needs.
