Yeah, framing is outrageously expensive. It seems everything is "custom" even for standard sized pictures. I wanted to make a frame collage of photos I took on a trip to put on my living room wall. 1 16x24, 2 8x12, 2 10x20, and it was $350 for basic materials. These are not odd sizes (maybe the 10x20). Needless to say, I haven't done this yet.
As for the poster, I created a cart but stopped short of making the purchase. I got an email saying they would extend the 35% discount for 2 more days. $40 ain't bad.
