What are some of the rules about the Internet that were taught to you but are now completely ignored?
For me, it was that the Internet never forgets and that you should never enter your real name. In my opinion, both of these rules are now completely ignored.
It's only expensive if you don't pay it in full every month. I've had my credit card for years and have paid $0.00 total for it whilst it generates at least 1% cash back or more depending on where used. Not much, but it adds up and makes it beneficial.
I have. My bank did a chargeback like they would if it was a credit card. I was told it would've been a lot harder to get my money back if my PIN was used. But, I've only seen that option available for in-person purchaees.
