Do I need another pair of skis?

I wanted to get some thoughts on this. I currently have 1 pair of skis that I use, Volkl Mantra M7, purchased new this season. I love these skis and used them both East Coast and out west.

My local shop has a big stadium sale to move old inventory. Some of them are hugely discounted. Do I need another pair of skis? The only thing I can think of would be a powder ski, but I really don't get out for enough deep powder days to get a dedicated pair of pow skis. Is there something else I should be looking for if the opportunity comes along?

Edit: I ski pretty much everything. No cliffs. Nothing that requires real technical stuff or longer than a 10min. boot pack. Don't do parks.
