Yes also in Switzerland. Many are 3 color eink so if something is on sale it's yellow or red.

Also very isef6as they for example state that one need to buy 2 for the discount etc.

Makes the life of the store employees a littler easier.

Innovation I would like to see is individual tracking of items in order to digitally track expiration dates.
