Marry me and I'll order all editions for you.
No but in all seriousness, it's not the end of the world if you don't buy the album right away. I know exactly how you feel, because I feel the same way about her single and album releases, I just HAVE to have them. If you've got plenty to spend, it's great and you can buy limited editions. But sometimes you're low on cash, and in that case the best strategy is to buy the CD-only overseas edition. It's really cheap that way, and you'll still support her!
I know it's a bit less exciting, but it'll still be fun holding the album in your hands and browsing through the booklet, right.
And if you
really can't afford it right now, buy it later. You can always add it to your order of her next single. Don't worry

Being an Ayu fan is hard with all the (expensive) material she chucks out, but we'll get through! I've actually lived like 2 years without Mirrorcle World, only got it recently and I was still happy with it.
Oh, and marry me anyway.
