Super cheap armor in shop

first post here so I’m not 100% sure this is the right topic, but while I was playing trunk I found this enchanted chain armor in a shop for only 1 gold. not sure if its that cheap because of the ponderous brand or if its just a bug. either way it is pretty funny

I imagine it’s because of the brand. Ponderous body armour that one actually wears generally is around +9, as I recall.
