This must be widespread, I am furnishing a house for the last couple of months and I had taken pictures of stuff in shops on my phone and saved them on my phone with the price. I went to a shop in Toughers Business Park yesterday to buy a kitchen table that I had seen back in October and taken a picture of. At the time it was 1540 euro and yesterday it was on "Sale" for 1500 euro after being reduced from around 1650 or something. When I asked the saleperson they told me that the supplier had increased their prices significantly in October. I accepted her explanation. I went upstairs to look at a bed I had taken a picture of and it was also on "sale" for the same amount as it had been when I was there last.
