I picked Squirtle as my starter pokemon so I got the Blastoiseite. I spent a lot of time bringing down my style to get the venusaurite for $10,000 but I can't get the guy to sell me the Charizardite which is what I really want. Is there a certain wait period before he will sell the 2nd one? I believe i'm going on 5 days now it's been and he still only talks about the stone he already sold me. Anyone have any clue as I have yet to see this asked anywhere?
How long do you have to wait between buying both Mega Stones from Stone Emporium Pokemon X (or Y)

According to this answer, you must have defeated the Elite Four in order for the Stone Emporium man to sell you the other stone.
I also picked a squirtle, but only bought my stones after I beat the Elite Four. I bought the venasaurite first, then he immediately sold me the charizardite stone afterwards.
