Potatoes bought: 12.3 pounds of Superior (plus will use some fridge potatoes, not sure what variety)

So yes, I bought only one type of potato this year:  Superior (from Ritchie's).  12.3 pounds worth, which cost a total of $21.39 including tax.

And I have ~10 potatoes in the fridge left over from last year that are great size and have started sprouting, so will use those too, whatever type they are (not sure which type).
