Adding an induction cooktop gives you a faster, safer way to sear and simmer without needing a gas line. You can tuck it away when you are done, which keeps your counter space clear for daily prep.
Wait for the holiday sales in November or December to grab the best price on both the unit and compatible pans. Shopping during these windows often knocks a significant chunk off the typical $300 price tag.
Remember that the 0% intro window is a deadline, not a gift. If you have a balance left over after the 18 months are up, you will start paying interest on whatever remains, which makes the cooktop much more expensive than you planned.
