I asked this question a while ago and got this answer....no help on 09-16-2012 04:20 PM We had a question the other day from someone who had -- if I remember correctly --- 3100 items in Marketplac and was wondering if there is an upper limit. As far as we can tell, no. The 102 items in my own store are so far below 3100 that I'm not worried. Your 78 items ought to be a snap. If you are having trouble listing things, take a very carefull look at the instructions to see where you might have gone wrong. If you can't find anything, you probably ought to file a support ticket under the category Marketplace >>> General Marketplace Issues. The instructions tell you to put extra items in subfolders than list them and you can list more that 20 but when I try to do that I can only list the 20 folders and can find no way to list the items on subfolders.
