Description of Bug

Hey guys, I use the project to support pricing things in my store. It looks like there is pricing data that is missing. I noticed this for the following sets.

Commander Legends Etched Foils (This happens periodically)
FROM CUTE TO BRUTE (PCTB)
Innistrad: Double Feature (DBL)
THE LIST (PLIST)

Thank you for looking into this!
