Posting in Market Place Sell

I want to do this correctly. This is one of the rules for listing, "EACH ITEM THAT IS MEANT TO BE SOLD SEPARATELY SHOULD BE POSTED SEPARATELY". I have a number of items Iwish to sell. Do I have to list each lens, each filter separately in it's own post? I can't post a list of all the items?

No, while it is not required that each item be posted separately, it is advised.

Here is the problem. If you post a long list, say 12 items, and half of them sell quickly, you may not post a new thread offering the remaining items until the requisite four weeks have passed. I would advise keeping the size of the list reasonable so that it does not become messy. It would be better to post three threads with four item each.
