I think she thought I wanted a refund, at the start, and didn't seem willing to do that.

I know that state law says that if the item is *marked* with a price, they have to honor that price. I thought that wasn't the case for items that are unmarked, but are in a labelled area, so that you can't just move stuff to a cheaper section and then pick it up. (In fact, I seem to recall that part of the negotation for grocery stores going price-sticker-less was that they had to have some sort of barcode-scanning stations that people could check prices at).

I'm also not clear that the sign was for that particular item - I think it was less informative about what it was for than what the price was.

But now I'm considering going back today and checking. :)
