Though kids would rather walk in a store and see something they like and then nagg their parents for it.

Yeah but that doesn't work for characters like Marth and Wii Fit Trainer, or a generic avatar like Villager, that kids can't immediately identify and obsess over. The online store would be for Nintendo's most loyal customers that are collecting, or buying because they love the series in question and are seeking it out. And anyways shopping is moving to digital slowly but surely anyways with kids being introduced to online devices and thus online shopping earlier and earlier in life.
