This is the perfect type of Groupon to buy to use for a birthday or Christmas gift.I know I will definitely be using it for Christmas gifts for Elias or Adeline.
You can put the Groupon toward shipping, which is awesome (and somewhat unusual).
Update: Also, I found that Yummie Tummie is offering a Groupon today. Their tanks are regularly $62, but with the Groupon you can get one for $31. I snatched one of these up for my mama tummy.
Go snatch these deals up now!
