My DD(11) was buying something in New Look today and was asked for her email address for the receipt. I said no as I don't think it's appropriate for her to be giving out her email address, but was told that they had "gone paperless" so that was the only option.
She hadn't actually tried on the item so we definitely wanted a receipt in case it needed to go back - so I got very cross at being forced to hand over my email.
I am completely in favour of cutting down on receipts and having the option to choose paper/email/none but AIBU to think one shouldn't be forced to hand over email addresses just to get a proof of an in person purchase?
