Groupon offers a $50 Red Envelope Credit for $25. That's the first such offer we've seen for Red Envelope from Groupon. (For further comparison, we saw a $40 credit for $20 in April.) The voucher excludes shipping costs, which start at $9.99. (Free shipping applies on orders over $49 via coupon code "FREESHIP49".) Deal expires January 1 and the credit is valid until February 26, 2014.
