I think that LivingSocial has pretty good deals. Somehow, I like it better than Groupon.
Some negatives are when I go to claim a LivingSocial coupon or Groupon, its really crowded or the merchant doesn't look so happy when I am there to use my voucher. I don't like the feeling of them not wanting to deliver the service with a pleasant smile. Truly, how can you really blame the business. Reading all the reviews, it seems apparent that the business loses out.
The other negative is that I always get buyer's remorse, every transaction, I wonder if it was a good buy. In any case, with the Groupons/LivingSocials, I feel like it's pressure buying. I've bought less LivingSocial coupons than Groupons but both I've had some expire and lost money on because I just couldn't use it in time, I couldn't make the drive over to where I bought the cupcakes from and I had to order 48 hours in advance.
I did find a website that I really like now called www.Stretche.com. It's all the good of Groupon/LivingSocial without the bad. No buyer's remorse because you don't need to buy, just "clip" a coupon for free.
