Plastic has some options.
Gas station closed but pumps still turned on, better have plastic. I live rural and while there is a 24 hour gas station there are a few others that are usually empty since they shut down late at night.
Need to do something over the phone or net, plastic works.
I don't buy gift cards or pre-paid stuff, sometimes for rewards or something I do wind up with them. I make sure to use them up.
Anything store specific is a waste of space to me.
Some prepaid stuff, all that I have dealt with, are good for x months before they start charging a monthly fee that autodeducts from the account. Waste of money to me.
Have a debit or credit card in your name, takes care of the prepaid stuff.
If you want plastic that is not in your name and not related to you, use what was mentioned above about paying a buck more.
