For just five more days you can get 15% off in the say it shop when you spend more than £5 and quote code FB15%. You just need to follow this blog or like the say it facebook page. Easy.
You get 15% off your entire order, which will be refunded after your purchase (as folksy doesn't actually have a discount code function). Just pop the code in the note to seller box at checkout.
If you've got a wedding coming up this summer, you could use the discount to save on some wedding cards.
