Bought an iPhone screen repair it said Groupon didnt expire until 2018 so I did not go for the repair until that weekend which was 4 days after. When I arrived the store owner explained I accidentally bought iPhone 6 instead of 6s screen repair. I tried to edit my order. I contacted Groupon customer service and they said I only had 3 days to realize my mistake and therefore they are sorry I lost $69.99. Thankfully the store owner let me pay him for difference although he said he would lose money from Groupon. In any case BEWARE!
