Digitec itself says the following:
"Regarding bots, by the way, we have a zero tolerance and follow up on suspicious orders. We also cancel orders from more than one card per person. We are also strict when it comes to orders from employees: They do not benefit from an early order window and do not receive any discounts."

I doesn’t look like Digitec allowed more than 1 unit per customer. I’d rather have this and not stand in line like they do in the US
