I'd like to be able to hide the price completely in my wish list (not just low/med/high). This way I can show my list to the guy behind the counter without them immediately knowing how much I think the card is worth.

again, this is a feature request..but I don't see how to make it that from a bug report..

To make something a feature request, select the "Type-FeatureRequest" label. You'll have to change it from the default "Type-Defect" label. Also, yes, this will get worked on, eventually.

This is now a setting in the preferences.
