Stuff for ladies is under garage sale so only need 1 threads for same item. If both have same item, you should closed one. It's advisable to open only 1 thread for an item to make no confusing later. If you sell BOOK A in 2 places, BUYER A and BUYER B want to buy BOOK A in that 2 places, to which one you should sell? For both of them BOOK A still no buyer yet because they refer to different threads. Got what I mean?

Or you can ask mod to merge.

admin/mod can move your thread to another location. That part of their job to make sure everything follow the forums law.

Just my 2 sen.

Not only can cause conflicts, I see some members open their sale in few place and end up no buyer or being close by mod without warning.

Lucky still don't happen to you because you able to manage your PM well.

Good luck in your sale.
