Yep, eBay finally recognized my potential and gave me the title I deserve.
...not really. I've just been seriously upping my sales over the last few months, and, as it turns out, I've been moving a lot more inventory than I thought. In order to qualify for power seller status, you have to sell at least $1000 worth of stuff each month. And you have to keep that up for 3 months to become a power seller, and you have to keep it up to maintain that status. I'm not entirely sure I'll be able to keep up with selling a thousand bucks a month, but I'm definitely going to try. For now, I'm just excited to have that little icon next to my name. :-)
As a shameless plug, you can check out my items for sale, if you want.
