I very much doubt that, considering how fierce the competition between retailers is, often fighting over single cents.
They’ve been in an eternal race for lower prices since they started competing.
Also, it literally applies here – since the fees for credit cards were reduced, ALDI and LIDL introduced payment with credit card (which wasn’t possible before at all at them). Same with REWE and coop.
How can you say it doesn’t apply if it literally happened.
The EU reduces your transaction costs by 2% for all retailers there's no way they will pass this on to the consumer eg my morning Starbucks did not get cheaper
