A new washer and dryer set turns a chore that takes all Saturday into something you can finish in a couple of hours. Laundry day stops being a major event and becomes a background task.
Labor Day weekend is one of the best times to buy because stores clear out old inventory for new models. Start looking now to see which features you actually need versus what is just extra fluff.
Remember that the 0% intro APR is a deadline, not a gift. If you still have a balance after 15 months, the lender will start charging interest on whatever is left, which will quickly make your new appliances much more expensive than you planned.
