Groupon's website had issues loading, which caused me to accidentally order four tickets to Water Country USA when I only needed 2. Instead of refunding me for the two tickets since it was completely their fault for having a sucky website, Groupon insisted that the fine print for the deal said "all sales were final." I told them I was done using Groupon if they would not refund me since there was no way I was going to use a website that has such an unreasonable refund policy, but they remained stubbornly insistent that all sales were final. Forget them!
