Refunding EoT items

Hello,
I was farming EoTs on my Prot Pala and decided that the next character I want to level is a shaman. After some time leveling it, I realised I am really not having fun with that class. Now my problem is, I bought [Champion Herod's Shoulder] (40 EoH), [Repurposed Lava Dredger] (65 EoH), and [Champion's Deathdealer Breastplate] (40 EoH). These items are on my character Handfire, Draenei Shaman.

Now, is it possible to refund those items and return the 145 EoH to me so I can decide better what to do with these emblems. I know the fault is mine for buying them without thinking about the class, but if this would be possiible I would be very thankful!

If 2 hours haven't passed yet you can refund it to the vendor, other than that there's nothing that can be done.

also you can't refund items after you have mailed them to your alt.
