Looking to buy the following mega stones using TBT bells:
Tyranitarite
Pinsirite
Mewtwonite X
Manectite

Pricing is flexible, but please be reasonable

I could get you all but the mewtwonite x if you're willing to wait a little bit (They're only available postgame and I haven't finished it sice I restarted, though it shouldn't take too long as I'm nearly finished)
Though i have absolutely no clue what mega stones are worth here...

Oops completely missed this until now — that would be great! I've only seen them being given away for free as well, so I have no idea of the real value. What do you think is a fair price?

Hi!
I am willing to give you a Mewtwonite X, along with the Mewtwo [once my friend trades it back, i lent it her to defeat the elite four] for.. um.. I'm actually looking for a mewtwonite Y since I HATE the way Mewtwo looks in X megaform. So.. an X mewtwonite for a Y mewtwonite would be fair to me.
