I Need One Thing

I have a little space in a dark corner of our living room where I do my workout everyday. For now I am content of the space I got since I don't do some really major workouts or I don't move a lot when I try to sweat. I do have an exercise bench, 5, 8 and metal weights which has adjustable weight on the metal that I could use. Now that I am getting tired of the same exercises I do everyday, I wish to do yoga at home and just watch videos on Youtube. While that can easily be found, I also want to buy me a yoga mat that won't cost me much. Right after this I am going to check on the best prices on yoga mats and hopefully I'll be able to buy one for myself.
