My mistake, thier GRACE

I have ordered dozens and dozen of times - I recently moved locations, and had accidentally shipped these poly mailers to my old address - I was hoping they would let me purchase again for the "deal" price, BUT they just shipped it to me again at NO CHARGE - that is what I call doing business right! I know they cannot offer this to everyone that makes a mistake, but I am thankful they saw the value of a loyal customer and helped out when needed - THANKS A MILLION! You guys rock!
