Groupon offers a coupon valid for a 16" x 20" Gallery-Wrapped Canvas from Canvas on Demand for $45 with free shipping. That's the lowest total price we could find by $13, although we saw this size canvas for $6 less two weeks ago. Deal ends March 9. The coupon is valid until June 5.

Also available is the 20" x 24" Canvas for $52 or the 24" x 36" Canvas for $75, both of which qualify for free shipping.
