When I worked in retail, I witnessed no shortage of people buying luxuries on credit. Not using a credit card merely for rewards points or other exclusive perks, but because they didn’t have enough money of their own. They had to use the credit limit available or they couldn’t buy. Worse, some had to get extra cards, because they already spent the money available in their primary cards. This is only ~1/10th as bad as getting payday loans, or 3 times as bad as a line of credit. Even the best of the three is still bad.
You are sacrificing greater future affordability than you gain.
Most purchases lose their effect over time. Some rapidly, drugs*; others gradually, a new smartphone. Clever excuse artists may claim they only use their credit for bigger, more functional purchases, like a used car or a bike. This is deceptive compartmentalization. Using up all of your non-credit spending is what causes you to need credit for the other purchases. This includes unpredicted emergency spending. You better be a legitimate psychic if you can only afford the spending you expect.
