What's the worst privacy compromise that you are willing to admit you make? - Sopuli

I’ve got to make a decision and want to take a room temperature check on what sacrifices people find acceptable for their own comfort.

Grocery store rewards programs. I know they are designed to link purchases to me, but the financial savings is worth the loss of privacy for me.
In many stores, they will swipe “a store card” for you at the register if you ask them. I believe I’ve even seen the option on some self-checkout stations. I’ve only had trouble with this once or twice. But it may be worth risking for the privacy (and monetary) savings.
This works for cases where just being a member gets a lower price, but at least some stores have digital coupons that need to be added to my account. This would not work with a generic card. It is definitely a good tip for stores where it does work though.
