Hmmm.... something seems too good to be true about this groupon. Plus the "may buy 4 additional as gifts." is sure to be abused.
Am I too skeptical?
Is there free shipping on online ordered? Maybe they'll get you there. Or maybe they will enforce the gift rule that shipping of items can't be to the same address.
Also only one can be applied per order so you'll be shopping there 5 times, once you do that you'll be a customer
