Just ordered personalised calendars, notebooks, posters and mugs... AND getting some items posted direct to the lucky recipient...AND got a £15 voucher off next purchase...AND bought credits for my account (which they top up anyway). I couldn't find a voucher, but think I was undercharged as the site was playing up (shhhhhhh).
Not a bad days work so far, especially since I have some people with unusual names who moan about never getting anything with their names on!
