Auction and buy stuff from ebay! There's many things to buy. If you got some useless items (maybe your pet died and you have their cage still for example), you can sell them here. But be careful, you don't know who's coming to pick up your item.
Been buying and selling on ebay for years. Be smart and read sellers feedback before buying or bidding. You can find many great deals. I do thank that their fees are getting a little out of hand but still the best place to sell.
There are some items that are sold on eBay that are not child appropriate. They may contain sexually explicit, violence, adult language, and drug references. I am a seller and buyer on eBay(7 yrs), and know I would want someone to tell me this before I let my child browse the site freely. Always ask questions before buying/bidding and make sure to check feedback rating and comments. Most of all have fun! eBay is an excellent way of making some extra needed money or "popping tags" ;) to save some money on things you may want or need. You can always find fun, family safe.. items on my seller account PLETH*OR*A_ITEMS :)
It is a good website where you can get most things you want but as with all auction sites you never really know who you are dealing with and when problems arise it is not exactly easy to get them resolved.
