I agree with the posts above.
Evo's carries many older models, that are still new, just never sold.
but timing is a key bit as-well, a good time to shop for last years stuff is right when the new stuff is being sold, or in the summer, or late spring when all the shops are trying to drop all of their old inventory.
I usually dont tell people about good stores to go (im selfish!!) because i like to get good deals there too, but then i realized how retarded that is, and i will tell you my favorite places to search.

I bought my Armada ARV's there, they were the 2008 model, but i bought them, towards the end of the 08 season, so i ended getting them for around $330, with some nice coupons.

Getboards is also another amazing place to go, good deals, very easy site to navigate.
But honsetly if you want to find good deals, Just start searching. Im not trying to be a dick, but thats how i find some of these online stores, just being bored on the internet. If you willing to put some time in to find a good deal, you will be rewarded.
