Hi guys, I saw someone mention this brand and went hunting for a promo code. Found FB30 on Facebook, and then guessed for INSTA40 and it came good - no idea how long it'll last, but it stacks with their already discounted prices.
I can't vouch for the product at all, but they come with a 12mo warranty against defects and they're an Australian business with local stock delivered via express post.
Normal price is $49.95 + post, cheapest available are these:
Silver Aviator style for $17.97 after 40% coupon + $9.95 post
Nice work!
