Ummm... there is an option that says ---> Can we do business
Then he says "if you have the coin"
Then say "I have the coin"
Then go to ingredients and by The deadra hearts
Simple

well if you cant buy daedra hearts from enthir what you could do is go to the shrine of mehrunes dagon and you can get 4 free daedra hearts. to get to it you need to do the daedric quest pieces of the past (its called something like that anyway) to start it you need the letter from the courier about the new museum in dawnstar you need to be level 20 for the letter btw.

also theres a daedra heart in jorrvaskr hope i helped

If none of the above worked, try reloading your save?

Hey mate,


You must trade with Enthir before you become an Archmage, or he will not trade with you. Several bugs have been noted with the dialog, but the default behavior seems to be, that if you trade with him before you become the Archmage, then you should continue to be able to trade with him.
An Archmage can unlock Enthir as a fence by completing the Thieves Guild quest Hard Answers.
During the dialog in Hard Answers, Enthir refers to himself as an Altmer when the player is asking about the history of the Falmer.
At some point after completing the Thieves Guild quests and becoming Arch-Mage, Enthir may lose his status as a "Fence"; despite having two separate dialogue options (one for his old retail mode and another for his fence mode) he will only ever buy non-stolen goods and be limited to the original 500 gold. (Not sure if this is related to doing the Hard Answers quest twice but Enthir lost the fence ability after I did it a second time).
If Enthir is in the courtyard of the College of Winterhold during a dragon attack, he will mostly just stand around and ignore it, even while he is personally being attacked. He may also occasionally applaud the dragon with the generic "My money's on the big one!" cheer but does not fight or flee.
