Today's email says 30 - 60%, so it looks like they are slowing down the discount on the stuff that's more likely to sell.
there are no specifics as to what is down to 60% off or what has stayed at 30% 0ff.
Edit by griffin...
As noted by some others, some stores are already closed, while some aren't at 40% yet... but most were from yesterday (July 19th).
