Just the facts: I measured four blinds incorrectly by one inch in width. That's right - Oops - my fault. However, when I contacted them (live chat) they would not allow me to return the blinds to cut off an inch. I worked for Sunshade Mini-blinds in Torrance CA while in college so I know it can be done without much effort. Very disappointed in the lack of customer service. The blinds shipped from Norman Window Fashions, LLC. I will buy my blinds from a local dealer that can provide customer service that exceeds my expectations.
