My hunter tamed a pet that didn't eat meat or fruit, and there wasn't a food vendor nearby that sold bread, so I sent some money to a lowbie alt to buy some bread in Stormwind and send it over.
I've done this before, and it never was a problem, but now my level 22 alt isn't allowed to buy level 65 food. A message pops up telling me I have to be level 65 before I can buy that food.
My husband rolled a new rogue, and wanted to buy her some level 5 vendor gear (it's only a few silvers and better then lootdrops/quest items) when he was level 4 to have it ready in his bags for when he dinged. He wasn't allowed to buy gear above his level either

Is it me, or is Blizzard starting to take this sort of hand holding to far? I understand the newbie tooltips are helpful for new players, and I'll adjust to the HUGE quest arrows and so on, but I should at least be able to buy things from vendors even if I can't use them yet.
