Air conditioners
Summer lasts for at least three months, even longer in areas with warmer weather. If you purchased an air conditioner in May to be ready for summer but it breaks down by August, you might have to other option but to have it repaired.
That’s because most retailers, including Walmart, have a 90-day return window, after which you’re simply stuck with a malfunctioning A/C. Costco, on the other hand, accepts air conditioners and refunds your purchase price, if you have the receipt. If not, you get the most recent price of the returned item, which might be lower. Still, it’s better than nothing, right?
