First you'd have to find a zero interest credit card that would allow you to buy something like this, and second you want to make damn sure you're going to pay it off in the allotted window, or you get charged your 20+% interest on the entire time as if you'd just used a normal card. Those things are designed so people who can't afford things buy them anyway, then get stuck paying a ton of interest when they continue to not be able to afford it.Don’t blame you. I already did it and got them yesterday. Amazing, you won’t regret it if you do (well not selling a kidney buy maybe a zero interest credit card).
And with the early stage recession we're in, and people losing their jobs all over, I'd be very careful about promising "Yes, I absolutely will pay off this in the next X months" if you don't already have a several months worth of emergency fund plus the cash on hand.
