Online store prices are outrageously high!

You can buy everything in the WoW cash shop with ingame gold.

Since when?

Edit:
So I JUST checked WoW. Nothing is purchasable with in-game gold. The purchase page for mounts, pets, everything looks like this-


You can buy a game-time token for cash and sell it for gold through the special Auction House menu made just for those transactions.
Some of the pets are tradeable (i.e. you can resell them to another player for gold, after you purchase them for cash) but they are the minority and they still need to be initially purchased from the store. With real money.
