Summer is the time for festivals.

Part of the experience includes shopping.

But what if there's a problem with the product after the festival is over and the vendor has left town?

It might sound like common sense, but there are some helpful reminders.

Before buying, know the company’s refund and exchange policy. Get the policy in writing, if possible.

Know where the company is located. Obtain the company’s physical location and telephone number, in case you need to return or exchange an item after the event.

If at all possible, shop around first. Keep in mind, however, that the least expensive item may not always be the best value. If you are making a large purchase, don’t be afraid to leave the fairgrounds to do some research.

Don’t be pressured to buy on the spot. After the demonstration or sales pitch, walk away from the sales person to give yourself some time to think about the purchase.

Pay with a credit card whenever possible for the most protection.

Know the limits of the “cooling-off rule.”

It’s important to note that the FTC’s “Cooling-off Rule,” allows people three days to cancel a purchase made away from the place of business, such as a fair or trade show.
