There is no limit to how many items you can bring to sell, so there's no limit on how much you can make.   Is it possible to make hundreds or thousands off of your gently used childrens items?  YES!

If you have more than 200 items, you will need to create a new account.  Each account allows 200 tags to be printed.  There is no limit to the number of accounts a seller can have (unless we close regsitration due to capacity constraints).
