Anyone know where I can sell dragon scales and dragonbones? I killed the first dragon and I am a mage. I can't carry them lol. I can't seem to find anyone in whiterun that will buy them from me

Quite a lot of vendors will take them. The Breton shop owner in Whirerun will buy them. I can't remember the name but it's near the market stalls.

General trade stores are your best bet, like the Breton's store mentioned in the post above mine. The store in Riverwood also buys them.

Might want to hold onto them. they're used to craft armor later.
