I have to say I'm finding this confusing as well. In the past, when they did "Blowout Clearance Prices", it said that against the individual item.
Now there seems to be a big banner at the top of the screen but, when you click on an item, it just says "Clearance Price" or "Sale Price". It would never occur to me that these items couldn't be returned for any reason other than defects.
I do think some clarification is needed, as many of the prices for things I looked at aren't that significant a saving. Not like the time they had a huge "Blowout" sale and things really were rock-bottom prices and were clearly labeled "Blowout Clearance Price".
