A couple of companies in Salt Lake City have an agreement with all of Utah's Ski Resorts and they can be found at Canyon Sports , http://www.skinsee.com/tickets.html and http://www.skitruck.com/product_listing.php?subcat=12 . You simply go there and buy them at the discounted price, that's it! Nothing else to buy, no pint of blood to leave. Sure they're hoping you will buy some of their other products and services while you are there, and many people do, but, its not necessary if you just want to buy cheap lift tickets.
Your savings for a ticket each day ranges from $6.00 up to $28.00 ....... this is a HUGE savings over a weeks time.
Hope you find this helpful. Comments are appreciated!
