I had vouchers, but couldn't book a day for service due to ignorance of the service... and living social didn't reply on my request right away (when I could ask to return money), then replied advising to contact more, but the person, answering me once after living Social contacted him, disappeared... and when I contacted Living Social again, they said "too late - the voucher expired". Another deal - they didn't mention important details about age limitation, so that voucher also was "lost money"... Also when I want to see deals in my area, they include deals 100+ km away...
