Loads of legit shops selling park skis now. Are you looking for skis from last season?
Loads of sick deals on last season's skis.
A few shops to note are:
Al's Ski Barn - www.untracked.com
Proctor Jones - www.proctorjones.com
Tramdock - www.tramdock.com
EvoGear - www.evogear.com
Sierra Skis - www.sierrasnowboard.com
Check out EvoGear's outlet, they usually have some good deals there... if the price is a bit high, email them, they usually match prices.
If you don't find what you want, have a look at:
Twin Tip Nation - www.twintipnation.com
Get Boards - www.getboards.com
GetBoards has received mixed reviews from people, some have received good service, others have not. They replied pretty quickly to some emails I sent them. Get Boards also matches prices, so if it's outta stock somewhere, then hit up Getboards.
