Great deal for regular contact lens users. I have purchased Groupon deal, voucher arrived in few hours, and placed order for my lenses straight away for £10.50 instead £50.50 regular price (for a total cost of 29.50). Don't vote cold just because it is Groupon as it will help many contact lens users. Lenson is a good retailer I used few times in the past (not as good as Lenstore, but come on, good price).
