Just in case you haven't seen they've brought back the points double up - only up to £100 (not sure what it used to be). But means you can swap £50 worth of points for £100 of vouchers which isn't bad!
We're nearly at the end of a long build and so have been saving up points for hopefully some new homeware stuff (pots and pans and towels etc) so pleased my £130 is now £180!
