Hi and thanks for your question!
Normally people go to eBay to get their items sold (hopefully), so pricing
your items with that in mind is your first step. Generally you can do one of two things.
1. Place the "opening bid" at the lowest acceptable price you will take for it. Therefore if you get at least one bid, you will be happy with getting that amount. Keep in mind, in my experience, buyers will often shy away from a high opening bid, even though it may well exceed that price eventually.
2. I've found this to be the better way: List a low opening bid price--not 99 cents, but something reasonable. For a $300 purse, I'd say around $50. Then set a "reserve price" that will be the lowest acceptable price you would take to sell the item. Customers can't see the reserve, only if the bids have met the reserve price or not. With a lower opening bid you can get many more individuals interested, and often, depending on the desire of your product, you can get a bidding war going and get a much better price in the end.
If your items are indeed new, never used, tags and all, make sure to make that known in your listing. If you can compete with another retailer's new price for the same item, your item will sell. Check ebay to see if they have any other similar or identical items and see how they are priced. I always do this before listing something and find a much better rate of success!
