You can browse several categories of products and send them e-mail if you are looking for something in particular and don't find it. I especially like their site because they have purchase options that allow you to order online and phone or fax your credit card number to them. Online auctioning has taken off as the internet offers the ultimate marketplace for buyers and sellers to meet and sell goods at what I believe is the world's largest flea market. I checked it out and immediately became enthralled with the process of submitting an online bid and watching to see the progress of the bidding over a period of days. There is no direct cost to buyers who register and bid for free.
Sellers pay a fee to list their goods for sale and a percentage of each sale goes to ebay.
Sellers generally provide a minimum bid and a description. I suggest deciding on a top price that you are willing to pay for an item before bidding so you don't break the budget. You may use a strategy where you bid midway between the current price and your top price so as not to pay too much for the item. You can also donate a toy to Toys for Tots at their web site. They offer a toy newsletter delivered via e-mail and a wish list for your kids to let Santa know their heart's desire.
