my neighbor is from saudi, so errr 6 months he gets a 400$ eyewear credit (doesn't even wear glasses, and you can get nonperscription sunglasses or w/e you want), so he brought me to get any pair i wanted and i only had to pay the tax on them. was pretty psyched
hit up ebay. i got some sweet one for around $150. Also my girlfriend found me a pair of legit old school one with the metal hinges for 50c at an op shop. The lenses were so scratched you couldn't see out of them but i got some aftermarket one (ebay) got them today. So stoaked, but yeah ebay is the best bet.
