Funny you should ask! I just got started as an eBay seller, and I'm having a great time. I haven't been on here as much lately because it's kept me very busy. My user name is the same as it is here, Dawnt91.
I've had lots of auctions close this week, so I've been really busy getting things closed out. I had a shower curtain sell for $41! I couldn't even sell it for $4 at our garage sale. It is beautiful though. I'm hoping to get some money in the mail this week so I can go to some garage sales this weekend. I need to get some more stuff out there. I was pretty bummed earlier this week because I took a lot of pictures of small items to sell (I don't have a digital camera yet, just a new scanner), and none of them turned out. $12 for processing and I couldn't use them! I was SO mad! I can't afford a digital camera, so I have to wait until I see my mom in a few weeks to borrow hers. These were cool items too, so that's even more depressing. I'm saving for a camera, but it'll be a while.
I love eBay, and it's a great way to make money if you're serious about it.
