Long shot I know but do you have a spare voucher by any chance?
:( My Wife keeps nicking my Ray Bans, so been looking to get another pair but keep missing deals. Having checked, RB2132 Polarised are £270 :O
Unfortunately no :( Ask a member of staff if they have any left in the back! I would certainly hunt one down for you lol. Hope you find one! I'm pretty sure they're valid for quite a while. If you've had a pack of vouchers through the post a few months back, there has been some at the bottom of them.
Does anyone know if these vouchers are still being given out? I spent a few pound earlier but that was at a self service till but would go back and buy something else at a manned till as the wife is looking at a pair costing £150
