Here is what a few of them had to say:
  • Mary did an excellent job. Shades have not been installed yet but i dont believe i have any worries that they will be installed before christmas. And installed profeffionally.

  • Mary was a very friendly and knowledgeable sales associate. She arrived as scheduled and was able to measure two windows and get the bid together quickly which was very competitive. 3 day blinds did a large job for me about 20 years ago and the blinds are still intact and like new condition. I recommend 3 Day Blinds.
    Lynn C - Saint Peters, MO - November 25, 2017

  • Mary was wonderful and informative. She understood my needs well and help me narrow down the selection. I eventually chose the shades that she originally recommended. I'm ready to order, but my husband would like to compare prices with a few places first.
