I was trying to purchase a groupon for a getaway on a friday afternoon, but the groupon app would not actually let me purchase the groupon on the dates it said were available... their customer service doesn't have any weekend hours, so they did not help (even though the site says they will get back to you within 24 hours), but groupons can expire over a weekend, so if you have a problem with a groupon on the weekend, don't even bother... you will most likely miss out on the deal
