The killer thing about yoga studios is they're so freakin' pricey. At this one, classes are $18 each. You can buy a 20-class pass for $259, which drops the per-class cost down to $12.95, which is still a lot! They offer a $129 monthly renewal, which isn't too bad if you manage to go yoga 2-3 times a week - but then you have to commit to six months.
I've got seven more sessions on the Groupon deal - and then from there, I'll have to decide. I can afford the $129 a month if I cut back on some of my frivolous spending - but compared to, say, a monthly gym membership, it's really expensive! Of course, I don't know that I would ever go to a gym regularly...so, there's that.
