No reviews so I was a bit afraid, but it all worked out!
Seems just like another site similar to Groupon, no reviews on TrustPilot yet so I was a bit afraid. In the end I bought 4 gift certificates for MontVR in Montreal (virtual Reality center) for half price, got a coupon code to use on MontVR's website, made the reservations there and entered the coupon codes, got the confirmations, all good!
