The 9/10 S has a 75¢ coupon for Domino sugar in the flip-top container.  The coupon doesn’t scan at Dollar Tree, but the manager pushed it through, ’cause it’s a flip-top container!  I checked the ones pictured on the coupon at Jewel (2/$4 on sale) and they do not look like flip open tops at all — I do see that they’ve shrunk the size to about 12 oz, though.
