Mommy Auctions just launched a few months ago and the listings subsequently are still on the rise, but the site already offers a chic, fun layout and simple, orderly navigation. It’s a great niche for those for whom Ebay seems too vast (plus, there’s no listing fee and the selling fees are less than that of Ebay) and Craigslist a little too personal. You can’t beat the benefits of reducing clutter while giving items a second life in the hands of fellow moms (and your own wallet).
