Here is this week’s Lowes ad that is valid through July 28, 2014. It is now Summer time at Lowe’s, which means ceiling fans, thermostats, and sprinklers are on sale! Lowes is the place to go for all your home improvement needs. Lowe’s publishes a weekly ad that is usually released on Thursdays in stores and online only. Occasionally they will have a circular in the Sunday newspaper.
