@dan - for those who are colour blind and bit old, I am having great difficulty in seeing the store prices as red/black and green/black. They are very hard to see - any chance they could be a little bigger and bolder in a different colour like WHITE? I am not moaning just disadvantaged! 
TIA
Yes please!
Yes please… I have to squint lol 
perhaps larger text also? Very small print on a floating window…
