Sold my nintendo dsi on ebay and i'm confused?

Don't knock it, honey, enjoy the money. People are very strange when it comes to buying those things on eBay. I bought a Nintendo DS Lite and at the time, people were bidding like crazy. Of course, it was before last Christmas in the U.S., so we are all nearly crazy, anyhow. Just enjoy the money and don't try to figure it out.
