I thought the word "entire" would cover it. How could we have worded it better?

Maybe something like this:

50% off entire store* *YES, everything in the store, NO EXCEPTIONS! Everything in the store is 50% off!

[that's not a joke. If you don't think it needs to be that clear, or explicit, or repetitive, taker a few minutes and browse some on and off line ads.

There are almost always an * or two listing the exceptions to "everything/storewide/etc"]
