Just a question, so once you become a Top Rated Seller, does it affect your 30 free listings? and is there any increase in fees? Thanks

to become TRS you first need to be a powersellr, thats the #1 requirement for TRS,

Powersellers and ebay Store members do Not get 30 free listings a month.

the  30 free listings are just for casual sellers, or those wanting to see if ebay is suitable for them.
