Sounds crap, but given you get 3x lenses, probably best off buying another pair, and you get a spare frame out the deal.
ECWC5U gives £5 off at Evans, to make them £37ish, if that helps.
Anyway, there seems to be a dearth of pics of people actually wearing the Guppys, so if you’re feeling sexy, Kimbers, any chance of a pic of you wearing them?
