It sorta seems like an extra 10% would make it 60%, but that's not how it works at my Hancocks. Say the regular price is $8.00/yd. and the 50% price is $4.00/yd. An additional 10% is .40 not .80, so it's actually another 5% off, not 10%. They take 10% off the total sale price, not the regular price. I racked my brain over that one day after thinking what a great deal I got, but the numbers in my head weren't workng with the total cost. Then I looked at the receipt and figured it out and said DUHHHHH!
