VR gear moves fast, but a solid headset should easily last you three to four years of gaming and virtual hangouts. The mistake most people make is buying right at launch, when retail prices peak and software is still buggy. Waiting until the newest hardware hits shelves usually knocks down the price of the previous model, which often shares the exact same game library anyway.
If you aim for that post-launch window, you can grab a reliable setup for around $500. Spreading that cost out over time keeps your budget steady, as long as you have a plan to pay off the hardware before interest enters the picture.
Keep in mind that a 0% intro APR is a firm deadline, not free money. If you still owe money when the 15-month window ends, the remaining balance starts racking up interest at the card's standard variable rate. Stick to the monthly payoff schedule so the hardware discount stays a real win.
