Didnt get a response via pm or the general section so I thought I'd try here...
Took my sister up to mountain high for her first day of boarding. I am a season pass holder and convinced her into buying a six pack. I told her to go to Active on Norco to pick up a six pack mostly to avoid the ticket lines. When she got home I commented on how it was a good deal for $179 and she mentioned it was $194.xx with tax.
A couple of my other friends got 6-packs through Defy boardshop for $179 and I confirmed that big 5 and sports chalet do not charge tax.
I called Active today and the manager Ben told me that "thats the way mt high set them up for us" and said there was nothing he could do.
