A high-efficiency dishwasher changes your nightly routine. No more pre-rinsing or re-washing cloudy glasses. The install usually takes a pro about two hours, but booking them is the tricky part. We want to aim for Labor Day because that is when appliance retailers clear out inventory to make room for next year's models.
Labor Day weekend is the sweet spot for discounts, but do not just settle for the store's preferred installer. Get at least three quotes from local plumbers or handymen. Sometimes the deal at a big box store includes hidden fees for new valves or hoses that an independent pro would just handle as part of the job.
This 18-month window is a deadline, not free money. If you still have a balance when the 0% for 18 months on purchases and balance transfers from date of account opening period ends, the standard interest rate kicks in on whatever is left. Pay it off before the clock runs out to keep the deal cheap.
