This has been bothering me for a long time, I learned from this article that you can disable receipt printing from the CVS app. Go into account settings and set email delivery to disable local print.
But then I would have to tell them my email address.
Get a dedicated email address/domain? Handy for lots of situations and makes you not have to worry about this again.
I use an older Gmail address that's already been spammed like crazy for things like this. If I need something from it, I can search the archive.
Right... your temporary, disposable e-mail address. Like mailinator.com, 10minutemail.com, and thousands of others. Out of the many online accounts I have, I don't think I have one tied back to my personal e-mail.
