As far as I understand the plan(s), you would only be charged additional fees IF
1. In the $2.95 Plan..you go over the number of included listings (15) at an additional charge of $.50 per listing over the limit.
AND/OR
2. You go over the limit in the plan for image hosting.(500 MB)
3. In the $9.95 Plan you would be charged an additional fee of $9.95 if you go over the (1GB) image hosting fees (at any time during the month). So keep that in mind.
From the Fee Schedule:
* Additional listings over 15 will be charged at $0.50 each.
** All users can purchase additional Image Hosting in 500 MB increments for $9.95/month. The first block of additional image hosting space for free users will be $2.95.
