Consiglio: If you can’t buy something outright, you don’t have the money to put it on a credit card

Other than large purchases like houses, cars, and sometimes phones now a good rule of them is to never buy something you couldn't pay for outright at the time of purchase. You never know what emergency might happen in the future and being late on credit card payments is a good way to kill your credit.

Especially with all the unknowns we have now with covid who even knows if you'll have a job next month. Stay safe everyone

EDIT: I'm not saying stay away from credit cards, if you're good with your money then by all means get one and use it because there are many perks. They are great to have as long as you're responsible. It's just an extra thing to think about before you make that big purchase.
