The profiteering greed was staggering; £20.99 for a pair of cheap masks, one of which was clearly out of a box of 100 or something as it had been repacked in a resealable sandwich bag! They clearly made more than £20 on this £21 sale - outrageous. I was so keen to get my daughter and myself out of there and back home, safe, I just taped my debit card without double checking the amount, which I accidentally read on the till as £2.99, not £20.99. In former times I would have returned for a refund, but I don’t want to make unnecessary trips. Thought I would use happycow to warn others, though.
