That day there was a sign out among the plants which said "starting today, reduced another 50% !"

Maybe the cashier was right, and we were wrong ? I am OK with 100% off

I came from Hong Kong, and figuring out discounted price is very simple.
There is no such terms as x% off, only discounted to y%.

Multiple discounted price = y1% * y2% ... of original
