Um, not buy and go somewhere else?

(This actually happened for real couple years ago, and I actually did drop my prospective purchase on the counter and left.)

Always a real email but one that is specific to their business.

No physical store has ever leaked my details though. Only tech companies (for a somewhat broad definition of "tech companies" -- I'm including Patreon lol)

Oh and one store I shop at a lot is also my employer so I use my work email there, the IT team can deal with all the crap they send me 😀

Depends if it's expensible for work purposes 😁.

Yes, and give them my work email, which (given past experience) may not exist in N years 😁

I give them a deliverable email but one that's specific to the vendor (storename@mydomain) so I can block it later if need be

Interestingly, generally the smaller the business the more respectful they are about how they use it

Honestly might be more of a USA-side thing physical stores asking for email addresses routinely.

None of the UK shops I regularly visit in person ask for email, receipts are physically printed unless declined.

The grocery stores don't ask at the till. Might have a leaflet elsewhere to pickup for "loyalty" scheme but they assume people will be prompted to do that with online orders rather than having time to push it in-store.

Esp. since the shift to self-service checkouts.

@neil two of my favorite neighborhood stores can't even print physical receipts, like at all.

That's less common than a place like a grocery store where they have older POS systems (my guess is due to accepting government benefits as payment). But the grocery store still wants it for coupons nowadays!

@neil
Do you think it is partly due to the legal frameworks / data protection?

Here I believe the rule is not to collect/retain information that is not required to complete a transaction or other process.

I also assume shops are not strictly allowed to share purchase history with any other stores not in the same chain or partner group.

Although most web advertising / analytics will probably claim grounds of "browsing data collected to improve the website performance / customer experience".

Depends.

A one-time-shopping place : lol, here's my trash-email

A supermarket I buy from every week and would like coupons from : ok, you can have an e-mail I check.

(Also I'm in the European Union, data protection is supposed to be the rule)(Not great though, but better than nothing at all)

definitely i give them a real email. The fact that is a SimpleLogin alias doesn't matter.

And TBH I prefer give out the email (which I can always filter) rather than the mobile phone number which is a real plague here in Italy.

This is something I don't have to deal with, but would probably give one that actually delivered to me if I had to.

I live in such a small town that the hardware store still runs on paper: cash, check, or set up a charge account that is tracked on hand written paper invoices. No digital payment capability at all.

i think this is rarer in the UK but i just give them a valid email (from a small selection depending on"trust").

What's the risk model/concern with giving them an email? i.e. why would you not?

Edit: strike that, I've just seen one of your later comments that implies "spam". Maybe it's a UK/EU thing but I've found stores are pretty good at honouring "Unsubscribe", and I'm fairly certain not selling on "email lists".

Little of column A little of column B for me.

I have email masks I can name/make up on the fly that do go to my real email, but can be set to filter out promotional emails, or just block all content (or let it through later). Plus it helps give me both unique logins and passwords for sites that collect email as an account name.

I'd say between the two options, I'm the first one, but I'm not REALLY in either camp.
