Awhile back i had the same thing .

I rang ebay support and they helped me out.

That was before Ebay Plus came out.

I signed up straight away ( its a great thing )

With Ebay plus i have been getting sell for $1 unlimited  and also 5 free listing today and 

Last week was 3 free listings  and $1 unlimited

I believe that you probably need to be a ebay plus member now to get these offers on a regular basis

I dont have a store !!!

If you have a store you might get different offers
