20-30 amy caps cost dollars individual jewelery listed listings month over pieces planning potentially route selling trial upload version word

Im not sure I understand this - SORRY! I see that the word UPLOAD is in caps so it makes me wonder what does that mean exactly? I am planning on selling jewelery - so potentially there could be 60+ different pieces listed- 60 or more individual listings. So I am wondering now, what the cost per month would be for this? I am just using the trial version right now but I may go a different route if this is going to cost over 20-30- dollars a month.

thanks-
Amy
