Stupid markdowns at Wal-Mart Supercenter

I came across these ridiculous markdowns a couple weeks ago.

"Was $1.58, now $1.56!"

"Was 70 cents, now 68 cents!"

I guess what frustrates me most about these pricing labels is not the lack of discount, but the implicit message that I am stupid enough to fall it.  How often do we turn off our minds and just grab whatever item has the "On Sale" sign next to it.  Clearly, more often than we think, if the marketing geniuses at Wal-Mart are up to this!
