I had gone to a large depot store and had service member cut measurements that I provided.   took it home and it was too long and too wide.  took it back and this time cut was to short and to narrow.  I spent lots of money on this item.  after three trips and no end results I gave up.   I went on wayfair and put in my measurements.  found it and was delivered, on time no less,  The blind fit like a glove. and was less than I spent at depot store.  as if wayfair cust service came to my house and fit it.  I received the blind on the exact same day that I was quoted.  I'm super happy with wayfair and the service.
