Jennifer in Macomb hit it right on the head (I think i bought something on ebay from her once, too!). If your kids' clothes and toys are name brand and in good condition (no stains, tears, heavy wear), you can sell them individually on ebay. If they are not name brand, but still cute, sell them in lots and you should have success. As she mentioned, though, it is IMPERATIVE that you do your ebay research first, though! Do an "advanced search" on ebay and check "completed listings only" to get a feel for what has sold recently and what it has sold for. Demand on ebay changes dramatically from month to month, so you really need to think about what you're selling and WHEN you are selling it. For example, I listed a pair of ladies' pink dress pants, and they would NOT sell in the fall, but when I listed them the following spring, they had 12 bidders! Take good photos, and remember to disclose as much about the item as possible-- if there is a small spot on the back of the leg of the pants but it's not that big of a deal, mention it and mention that it's not that big of a deal. Setting up a PayPal account will be helpful, too, if you do not already have one. NEVER EVER EVER ship anything without getting payment first and making sure it clears (this seems obvious, I know, but I have known experienced sellers who have actually made this mistake once). ALso, if you don't want to go to the post office to ship everyday (I don't get my stuff picked up because my mail doesn't come until late in the afternoon), list all your items on the same day and mention in your listing that you only go to the post office on certain days.
Good luck and have fun!
