Didn’t realise but apparently the price cards aren’t paper anymore, they’re e-ink now. Saw one change in front of my eyes and I thought I was seeing things! Must be some sort of dynamic pricing thing they do so that they’re always cheaper than whoever is cheapest or something.
Best I can give you is low quality videos with a max length of 2:20 that occasionally lose audio sync, and sometimes the audio decides it doesn’t want to work at all.
