Describe the problem. Be as specific as possible!:
Look at picture to understand what I am describing.
Basically hover over the area in picture shows the expansion is 4,000 NX for all of them.
Yet in the cash shop it's more expensive.
Trying to purchase the 4,000 NX slot yields this misleading purchase box. (see picture 2)
I haven't purchased any, as you can tell I am planning to spend the rest of my NX wisely... (haha)
