Where can I find mylar?

I checked home depot and they don't have any mylar, where else can I get mylar other than a growshop (closest one is a 45 minute drive)?

Thank you in advance,

You can get mylar giftwrap at a regular store like Wally World. Of course to get as much as you'll need, it's gonna cost ya.

Sup ,
The sporting goods dept. at wal mart / target / meijers etc ...
5ft x 7ft sheets for 1.99 . survival blankets for camping .

I ended up biting the bullet and driving 45 mins to a hydro store to buy 25'x4' of good quality 1mm mylar and some Liquid Karma too. Thanks for the advice, I might have to grab a emergency blanket for my car and then 1 for my grow area door I am making (making a lightproof flap with velcro)
