Pewter or cinnamon pastel?

Im a bit confused, are pewter and cinnamon pastel the same morph?
I was looking at a breeder site and they had both listed at different prices.
Im on the lookout for a cinny pastel or cinny het albino female.

They should be the same thing. Who's website has them listed as different things?

It may also be that one is a black pewter, which is black pastel instead of cinnamon?

They used to call cinnamons "cinnamon pastels". The pastel part got dropped over time but once in a while I see a cinnamon listed as a cinnamon pastel. A Pewter is the cinnamon gene plus the pastel gene.
