There are so many amazing online deals on appliances, this one might be impossible to resist. But for a number of reasons, buying them in-store is still a safer bet. So much could go wrong while shipping a refrigerator or dishwasher, and if it arrives damaged you'll have to work out how to return that enormous package — and you might have to pay for it if you can't prove when the damage occurred.
Service is another aspect to consider. If you buy in a store, you'll be able to talk to the salesperson about delivery, installation, returns and warranties. Online, you'll have to closely analyze the fine print, and you'll probably end up having to make a call or visit a store anyway if you need to clarify things. Check out the shipping costs, which could be pretty steep. Will you have to make your own arrangements for installation? The last thing you want is a massive refrigerator box on your doorstep and no way to get it inside. Your friends will probably not appreciate having to come over and help you drag it into your kitchen and then figure out how to install it. If you can't understand the setup instructions, you might have to hire someone to do it for you. All in all, it could be a whole lot of hassle for a small bit of savings.
