Mylar?

OO im 99% sure you cant find it at wally world. the cheapest and best way is go to your dollar store and pick up a wrapping paper called "polly warap". it looks really shinny...BUY IT!!!!
 
You can find it in the Camping section, Its called a Camping Blanket and sells for $1.99. I have two in my grow room and they work just fine.
