I was using my TJ Maxx/Marshalls, etc. Gift Card while shopping at my local stores today and they have TONS of yoga mats - including 2 black Manduka Pros for $49.99. That is a great price for a Manduka...I have two Pros already (one bought from Target for $60). I actually had it in my cart but thought why do I need another $$ Manduka? So I thought I'd take a gamble for $19.99 and buy a Gaiam Insta Grip mat (6 MM) that was more cushy, stickier, and prettier!
It boasts of "instant traction in any pose". (I'm getting tired of black! My other Manduka is light blue which is pretty but I keep it upstairs and don't use it as often). It seems my black Manduka is losing its' stickiness. I'll report back how I like it....
Just thought I'd share if you're looking for a yoga mat....they also have lots of other workout related items.
