£32.50 off at the sunglasses-shop.co.uk - basically this site allows you to buy "vouchers" at various websites to get discounts, this one is £17.50 for a £50 voucher, so you save £32.50. It's all pretty legit, they've run it a few times now. Last time I grabbed an Oakley rucksack for not very many pennies.
It doesn't include postage, so bear that in mind but there's quite a lot of cool stuff on there, including prescription glasses for those of us without pilot-like 20/10 vision.
