Bath & Body Works | Semi Annual Sale Savings Chart

I made an "at a glance" chart for shopping the sale showing me the price I will pay for the different price points.  Of course I know easy math, but I wanted to have something handy as I am grabbing all I wanted.  The prices shown below are what we will pay....for both 50% off items as well as 75% off items.  HAPPY SHOPPING!
