There are no catches to the deal, aside from the fact that you’ll probably have to sign up to be on the Living Social mailing list, which is entirely easy to opt out of, after you’ve ordered and printed out your 90% off voucher. That’s a small hassle for a meal that you could have delivered to your door for the change that you have collected underneath your couch cushion. Just don’t forget to tip the delivery guy (preferably NOT in change).
