I was thinking of ordering a mask to prevent my sisters from killing me (certain now that's their plan). UK Meds - £15 for a mask that is normally £2.99? Disgrace.

You can make your own which are just as effective.

I did make my own (well, not quite yet, but watched a youtube video and thankfully have a stapler and elastic bands. High five.)
