Whats the difference between WN2500RP-100NAS and -100PAS?

Is there a difference between the two models? (WN2500RP-100PAS) and (WN2500RP-100NAS)?

I was looking online on www.bestbuy.ca and it had both on the site for different pricing.

Huge difference in pricing, from $79.99 - $126.99.

So is there a difference?
