Living Social cuts $5 off orders of $15 or more via coupon code "TAXDAY5". That's tied with our mention from a month ago as the best dollar-off coupon we've seen from Living Social in over a year. (We saw 20% off sitewide a week ago.) Deal ends April 15.
Beware of LivingSocial (and organizations like Groupon)--these companies will sell you a discount but won't help you if things go wrong. In the sale, buyer contracts with the retaiier NOT LivSoc to get the deal, so if the merchant doesn't honor the deal, your only recourse is with merchant NOT LivSoc (or Groupon etc).
