As one of its daily deals, Groupon offers a $30 AllPosters Credit
or a $50 credit
. That's at least $15 off, tied with our December mention, and the best AllPosters credit we've seen from Groupon this year. Shipping is not included, although the credit may be applied toward shipping. Voucher expires January 29, 2014. Deal ends August 8 at 12:59 am.
