There's a lot of those daily deal sites out there, and some of them I enjoy more than others. I don't make use of them too often - we're far enough outside the big city to make some of the ones I'd really like not practical, like traveling weekly for dance lessons - but for the one-time-use events, they can be really great.
Shhh, don't tell, but I bought one of my husband's birthday presents this way. I think he'll really like it - and I got a great deal!
I've had really good luck with Groupon. I haven't used the Groupon Now site, but it seems to be very similar - just with a faster turnover time.
What do you think of these kinds of sites? Have you used them? Found any great deals?
