eBay and Craigslist finds

What does it mean to exceed your selling limit on eBay?

Well last month (september) i sold 3 items on ebay of a total of £450. I have an monthly 650 limit (
You can sell up to 10 items or up to £650.00 per month, whichever comes first. from ebay)
So thus i'm not going to sell this for 200 obviously not, so put it on gumtree for 600

... and as if by magic, it appears.
