I believe the OP was noting that they finance items on a Same as Cash basis, paying off the balance before the due date of the SAC period.

I do this myself on all major purchases. I have the money already set aside and dedicated to paying off that debt in an interest-bearing account. I generally divide the purchase by the numbers of months minus two (so I always pay the balance two months prior to the promotional end date). So say my iMac 5K at 24 months at $4000, I pay $182 a month so the balance is paid in 22 months and I am earning interest over that period.





It's not hard, but there are benefits to me in using the CC and floating that balance in an interest-bearing account for the 20-30 days that I would not get if I paid cash up-front. Your mileage may vary.

Ahh, I didn't realize folks were talking about 0% interest credit cards. I've never tried to set up a purchase like that with a 24 month 0% interest period. It could certainly make me a bit of money doing it that way.

One place I won't use the Card, though, is Costco, because the only credit or charge card they accept is Visa.

Wrong, Costcto stores accept Apple Pay.
Costco won't take your physical Mastercard Apple card, but will take your phone's digital wallet as payment - any card type.
Costco won't take your MC online.
 
Apparently illegal in some cities or states. Tender Greens does not accept cash


Illegal everywhere in the US - dollars and coins are legal tender for all debts public and private. Moreover, cashiers should be wearing gloves anyway.

Oddly in the UK, cash is not legal tender and there is no obligation accept it. Moreover, the currency from different countries in the UK have different statuses. That's a real PITA if you have Scottish notes and you want to by things in England. That's one thing that definitely should be changed.
