First of all, loving k2.

Is there any way possible to have an item displayed in 2 different categories without duplicating it?

with this link you download a plugin that permits you choose additional categories for your items.

Thank you very much mili! Just what I was looking for! :) William, Thank you as well. Though, $49.00 is a pretty high price tag for that particular plugin.
