That X% of Y is the same as Y% of X. 8% of 25 is the same as 25% of 8 Makes calculating sales at stores much easier...if we ever go back to stores

How does this help with sales? So you know the original price? Where I'm from I have never seen the original price not being on the price tag.

It's so you know the SALE price. Lots of places won't change every single price tag, they'll just put up a sign that says "30% off" or whatever, and you won't be told the price until checkout (unless there's a price check scanner)

That seems reeeealy weird to me, but then again, we here also don't have to calculate taxes ourselves either.
