I went to my local store to get prints and ended up not using them due to cost of prints for the size I wanted. I needed 2 10x30 prints for Christmas and the local shop wanted $67 for each print. I simply cant afford that, maybe their smaller prints will be more affordable. Their prints are a lot cheaper if you also get them to frame the prints but I also make my own frames
