Here is another one on Groupon (Boston).
For $25, you get $75 worth of holiday cards.
For $40, you get $100 worth of holiday cards.
For $50, you get $120 worth of holiday cards.
And, the Groupon is valid toward tax and shipping! There is a limit of 1 per person, but you can buy 1 additional as a gift. These are ONLY good for cards.
