I had the most POSITIVE experience with Wallpaper mural. I accidentally ordered the wrong size and material and crop of the wallpaper I wanted. I called them and they helped me get refunded and order exactly what I needed. In addition, I had very specific requests on how the mural would fit around two small windows on my wall and they helped customize the paper's cropping to the exact dimensions of my wall. The person who helped install the mural also commented on how high quality the paper was.
