Aarons also does their "Buy one frame get a second frame for a Penny" sales twice a year so it pays to look for these and stock up.
Too bad the sale isn't this month; I just spent $60 on three 16x20 'Signature' frames, but they are pretty nice black lacquered wood with glass. I couldn't wait for the sale as I am submitting 3 pieces this weekend to the Pasadena Society of Artists membership drive. The photo "Alien" in the gallery section is one of the pics I'm submitting. Wish me luck!
