I have been with Aeria for quite a long time. With that in mind, I would like to say that Aeria doesn't always follow the original version of the CS. Most of the items will be similar, but Aeria has a tendency to introduce their own items, change prices and item durations, or put items into the CS in a different order from the JP shop. Because of that, prices in CS and in the game will slightly defer from the JP version, even if the items are mostly the same.
