Need YOUR HELP with ordering AYU's discs in JAPANESE INTERNET SHOPS

[ayuMIV]

Ohayo, minna-san!
Good morning, dear forummates, dear forum-chans and forum-kuns!

Unfortunately I had a bad luck to born in Russia... While my body is still here, my soul for about 2 years wants to fly away to Japan Till now still unsuccessfully

So...

Recently I decided to start buying Ayu's discs in Japanese Internet Shops. For this purpose I ordered special Visa e-c@rd in VTB24 (one of russians banks).
Then the question "what online shop should I choose?" appeared.
So actually what shop to choose to buy high quality Ayu's discs?
CDJAPAN?
Play-Asia?
YesAsia?
Give me the peace of advice, please!
What I need from the shop?
-Availability of Ayu's discs,
-availability to order them from Russia and to get it here from there,
-reliability in case of shipping my orders and accurate billing,
-trustworthiness.
In other words what shop can offer the highest quality with the lowest price?

So I wish those who has such an "ordering experience" will help me and give their piece of advice! What shop to choose? What problems I can encounter? And etc. Arigatou!!!

Oh! And if you are from Russia your experience and help will be priceless for me!
