Wipbox is a relatively new service that helps people sell things on Craigslist and eBay. Wipbox charges a small fee to help you put together a really slick-looking listing and figure out some of the subtle aspects of getting an item to sell quickly based on what category and service it's listed in. If you've ever wanted to sell something on either of the two classifieds services but have been unsure about a good starting price or the best way to convey the product information, Wipbox does the heavy lifting for you.

To get started quickly, you can do a search for your item. It's not free at $0.25 a pop, but it gives you the starting and closing costs for your item in various categories (for eBay) or locales (for Craigslist). For example, if you're here in San Francisco, your item might fetch more money in surrounding neighborhoods. Likewise, on eBay, putting it in a different category can dramatically improve the closing price. You're paying Wipbox to do the legwork.

Search results for a Motorola Razr on eBay came up with pricing results in five different categories. The ones with the highest sell prices (the blue bars) means selling it in that category will net more payback.

In testing, we came across some skewed numbers for certain search items. For eBay, it was likely due to auctioneers incorrectly labeling their items or adding extra words to their titles to boost search engine presence. For Craigslist, we ran into problems with the search grouping together multiple SKUs. For example, a search for an Xbox 360 pulled in results with a difference of about a hundred dollars due to the system having two versions, each at a different price. For popular items such as iPods though, drilling down to the specific model number helped with these issues.

Wipbox bases its statistics on 30 days of eBay listings, and a full week of Craigslist sales, so whatever information you're getting is fairly current for market value. To find general price ranges for online auctions, there's also Mpire, a service that tracks auction prices on eBay to show you whether or not it's in demand--a little bit like Farecast does for airplane tickets.

The real catch to using Wipbox is its listing creator. Wipbox will pull in a description, user reviews, and specifics from Amazon.com. You can either pay $0.15 to have this information posted straight to your listing, or copy and paste the code field by field into eBay or Craigslist's listing creation box for free.
