Read this if SE doesn't want your money!!!

[Raist]

Keep in mind that Crysta may not show up as an option if SE has chosen not to make it available for your region.

They really need to provide some sort of guide as to which regions do/don't have Crysta available to them--it's caused a lot of headaches over the years.

If Crysta is available to you as a payment option, you can also use the Ultimate Game Card codes as well (add the code via the Ultimate Pay option, there is a separate tab for entering your UGC code). You can get the physical cards at local store, or buy the codes at a number of places online.
