Generally they offer deals which are available anyway, I've only used them once for a vistaprint offer whereby if you pay them £12 they give you £40 worth of credit but you have to pay full price for everything so you can't apply offers that vistaprint have. In the end I paid a total of £36 for some cards & calendars which would have cost £38 with the standard vistaprint offers so I saved a whopping £2 whereas it made out that I'd be saving £28.
