Or any other group deal buying site. I've found myself using Living Social more often than not, but regardless of where I've bought I've had some positive and negative experiences.
The Positive
One time I had a credit on my account for $10 for some reason unbeknownst to me. I searched for the cheapest deals they had, and found one for an ice cream place we love. $5 for $10 worth of sweets. I got two of them. $20 worth of ice cream for free. Instant awesome family time.
I also got an oil change/tire rotation package. It sounds pretty sweet, but we'll have to see how it goes. $33 for 3 oil changes, 2 tire rotations, and some other thing that I don't even know what it is.
Also, I got to preorder some seats for when we went to Yo Gabba Gabba a few months ago. I was so sure they were going to sell out. Which leads me into the negative.
The Negative
When I ordered those tickets, I didn't get to pick specifically where they were. Just a general section. They were great seats, but I found out the night of the show that they weren't sold out. And for $15 more (total) I could have ordered from the venue itself and picked where we sat. Maybe gotten a bit more center. It would have been worth the $15 to me.
Another time I ordered a photo package at a studio. When I got there, I found out they regularly have better deals than the Groupon I bought. It was marked 89% off on the site or something crazy like that, but I could have gotten 95% percent off by using the store's regular sale. So for things that are regularly "marked down," it might be better to just go check it out yourself.
Another time I ordered a photo cards. Or the opportunity to make some. I got the software and decided it sucked. So I resold my voucher for its full value. After that, I wrote a whole post about
how you can resell those vouchers. It was info I was glad I had.
Oh, and recently Living Social got hacked. So if you have an account, go change your password if you haven't already. I'm still kind of worried about what information may have been obtained.
