Here is this week’s Lowes Ad. This Lowes ad is valid April 17 – 21, 2014. It is now Spring time at Lowe’s, which means plants, dirt, flowers, & pavers 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.
