Looking for sweet potatoes (and maybe cranberries? (Bogotá)

Hi all,

We are looking for some sweet potatoes for Thanksgiving, and since are new to Bogota, not sure where to look! Any suggestions? I'd love to find even some canned cranberry sauce too but haven't seen either sweet potatoes or cranberry anything yet at Carulla/Colsubsidio/Suftifruver. Maybe I am looking in the wrong places? Any suggestions would be great!
