> When I used a credit card at home depot self checkout I was asked if I wanted to have the receipt sent to a specific email address I entered previously online. Creepy. So I started using cash only.

A lot of retailers do that now. They match first 6/last 4 in store against your online account to match receipts up. Walmart is a big one now with that implemented across their self-checkouts (and eventually pushed onto the registers with their new software/hardware upgrade push).

Slightly makes sense if they haven’t loaded every machine up with a full cash load. Plus some lanes might “accidentally” be turned on without any cash in them and not put into a “cards only” state.
