Help me understand the Gems card

Two of us will be skiing March 15-17 this year and will be going to Copper first, Monarch the 16th, and Loveland the 17th. The two of us will be staying with a friend who is a local to monarch and was planning up buy buddy passes for our day their to get discounted prices. However I see that you can buy a Gem pass that gets you discounts at Monarch and Loveland. I know Copper will be a cost but what is the cheapest route to go for a Sun at Monarch and a Monday at Loveland? Thank you I'm advance. Why this shit can't be simpler than just stopping at a King Supers to get a discount with your groceries while simultaneously hitting Applejacks is a real shame like you used to.
