I for one was signed up for Elkjøp kundeklubb membership unbeknownst to me. It happened when I was picking up a water cooker. Seller asked if I would like an electronic receipt and asked me for my email. That was in Elkjøp at Solsiden in Trondheim.

The more annoying is that I gave him my regular email address and not a generated alias that I always give to companies.

Was super pissed when spam started landing on my main address.

So no, not plenty alternatives here.

If I need to buy something at El Giganten (Danish version) I speak English when paying, and tell them I'm a tourist and don't want to give them a phone number or email. They can print a paper receipt.

But I only buy from there if it's the only option. (Other than Amazon, which I refuse to use at all.)
