Went to Ikea yesterday at last and bought some Trofast units and something very similar to Expedit called Bonde which is being discontinued so got it at bargain price. I now have 16 holes to fill and didn't like any of the the Ikea boxes which seem very expensive when you need to buy 16 of them, and not great quality. I'm sure that while doing research on here I came across people mentioning that you can find much cheaper boxes to fit ie from Argos or Sainsburys. Any suggestions gratefully received!
