I often take photos of humorous department/grocery store signs. This one I took years ago but missed putting it up. This is in the famed Galleries Lafayette in Paris, a store that charges enough for it's clothes to pay for a personal mathematician to go around and correct signs. It appears he was off that day.

So this 50% off of free, is that before or after taxes? And also is there a chance the price will go down further because I've heard rumors that next week it will be 60% off of free.

I'm sure this is a translation error but still it's funny. Free minus 50%, discount already deducted. You know because it's so hard to calculate. 

While we were there we saw a dress that was 9,000 Euros, about $13,500 U.S. dollars at the time. Too bad that wasn't 50% off of free.
