I just straight-up ignore "sale" claims now, unless I have personal experience that says this really is a sale. This is mostly limited to groceries where I definitely know that the $4 bag of chips really is on sale at $1.50. Along with all the active deception, I also just count all the times I've gone price shopping for non-trivial things and the prices I see and how festooned with the word "sale" the page is is simply uncorrelated.
