I'm not quite sure what you mean here. Link 1 shows that they sell for .33 all the time. Links 2, 3, 4, and 5 show that it's possible to get .44 for them. It says it right in the notes for this suggestion.

The second link shows a sale of a few days ago in the comments. They're not put up for this price very often because it's a somewhat odd price, and it's above the current suggested price. But they do sell at that price.
