Width of Roll Changed

I had ordered these roll labels many times in the past with no issues, but Sticker Mule decided to change the width of their spooling rolls without notice. These new spooling rolls are 3 inches wide now and no longer fit into the dispensers I have. When notified, they told me they changed to improve their production. I am stuck with thousands of labels I cannot use as they do not fit into the dispenser.
