Swiggle works to get you your money back or refunds when prices drop after you buy something from over 50 retailers. Most retailers and many credit cards have a price drop guarantee, but until now, it's been up to you to check each store for lower prices and try to get the refund yourself. How do we do it? Swiggle constantly looks for lower prices on the items you've already purchased. When it finds a better price, Swiggle contacts the retailer and gets you a refund on the price difference - all without you even lifting a finger.
