home depot or lowes, lols.

i wouldnt say its not worth it, let me rephrase that. its only worth it if youre really struggling to get the very last bit of weight off your car. id do simple stuff like a/c, smog, ps, pw, and sound damp. material first, then interior shit. after that if you still really need to shave a few more pounds, do lexan.

idk how it is in your car, but my rear three windows hardly weigh anything as it is...
