Cardcaptor Sakura - Sakura ch. - Promo

I've just found out this promo!
I did't know that this set has promos!
Has anyone got other info?
Do other promo cards exist?

It is usual in Japan to do "Promotion Card" before the collection come out. That a "Publicity card" in reality. I have the same for the Movie 2 collection. That's the difference between "Promo Cards" (=gift card) and "Promotion Card" (=publicity card). Do you understand? That's not easy to explain sorry...

Edit: You see on the card there is the price for one pack and the date the collection comes out ;P

Yes, I have the Promo from Movie 2 too
I know the difference between the two kind of promo
but I didn't know that this set has promos, any kind of them
It's hard to find out, because it's not written anywhere, not on the boxes, nor often on the official webpages
It's always a discovery... by chance

I didn't know too that there is a promotion card in this collection I always try to have all promotion cards too, but there are really hard to find

Do you think that having No.10 written on the back just mean it's a promo version of the card No.10?
or we have to suppose there are other promo?
the promo usually have its numeration system, different from the regs set, but here the cards is exactly the same as No.10...

I hope that it exist only this one... I don't know in fact, but 10 promotion card, that's a bit too much... so I think that's the promotion card of the n°10.
