Free Fitness Classes

Has anyone here tried classpass? You pay a monthly fee (£25 in the UK, not sure about other countries), and you can use it to go to fitness classes in your city like yoga, HIIT, barre etc. I'm currently trying it out as an alternative to a gym membership, because I really don't use my gym enough but I would love to go to some yoga classes, and I can't really afford them at the moment.

If anyone wants to try it out, we both get £30 off (equivalent to 5-7 free classes) if you use my link http://class.ps/njtZL

I'm not 100% sure hat the link will work if you are in another country- can someone let me know if they try it and it works?
