Huge Scam.
You don't pay for products, but for vouchers. Vouchers that they are supposed to send to the retailer (Home Discount in our case) so that they can proceed with your order. The vouchers never get there. If you ask the retailer, they obviously say that they cannot do anything because they didn't receive the order from Living Social. If you ask Living Social... well, good luck asking them, they have a perfectly created funnel in their call center that ensures that you can NEVER talk to anyone, asking for random numbers that you don't have that make you start always all over again. Long story short: you pay, you don't get your product, and they don't pay back. Please don't waste your time and/or money here
