Right now at Old Navy they are having a RIDICULOUS sale with an extra 30% off clearance at checkout. Shipping is FREE if you grab $50 or more and join their rewards program (free to join). You can always do returns at your local store if you need to. Some items have an extra 40% off clearance too.
To find the clearance section for what you need click on “Sale” on the menu and go down to “Clearance”. The pictures above are items in the baby sale but there are clearance deals in every department. I put some random stuff from the women’s department in a cart below for you to see some of the prices there too.
