Bought a Groupon and would have loved to use it! I bought the Groupon in April and called pretty frequently the first few weeks and left messages. Someone did eventually call back and left a message (called around 11 AM on a weekday, I was at work so couldn't answer). I called back same day and tried again repeatedly. Never  got another call back. Had to get a refund from Groupon :( Would have loved to have my windows tinting in April or May. Now it's already 120* and I need them down pronto! Looking elsewhere.
