Multisite: Copying blog post between sites

Hello,

is there a plugin around that would let me take a group of post from blog A and import them to blog B some h ow?

I have a retail site and a separate wholesale site that i manage and I have to enter all the products in the wholesale site over again. Im wondering is the a way to take the a way to take product post from Blog A to Blog B.

both these sites are on a multisite install of wp.

i only need certain post. not all of them. and I have to make sure that other staff can do this so i dont have to, every time there is a new item to be added to the wholesale site.

so if anybody knows about a plugin solution out there. Id be very grateful.

thanks!
