We had this in Greece and it was great. Then you could order through the aggregator itself. Then it got its own delivery service that shops could use (still better than all other delivery companies). Then shops were added that don’t have their own site nor a physical shop. Now it’s trying to expand to other countries and there is a subscription that gives you lower delivery fees. It’s still good and most people buy stuff from there but it’s clear it’s trying to become Amazon and I’m afraid most similar centralized services will go this way sooner or later.
