where i can buy ubuntu sticker ?

"Ubuntu Stickers" can be purchased from the Canonical store, here: http://shop.canonical.com/product_info.php?products_id=718

They typically ship everywhere, but expect high shipping costs if you're not in the UK or something (shipping was $14 something just to ship me two CDs from the Canonical store, probably because of international shipping costs since I'm in the USA).

i have to pay for tranpotation or not
yes for my country this sticker is very expensive i have to pay 50-100 bht

If I wanted a sticker, it'd cost me $11.45 just for shipping. I'm not spending $11.45 (US) to ship a $4 sticker to me either. Unfortunately, that's the only *official* source to get ubuntu stickers, since that symbol is i think somewhat rights-to-use restricted... (my original answer, though, is correct in that it *is* the answer of "where to get stickers)

Are there any stationers nearby where you can take the images and make your own?

never mind i just ask because i want to know i'll buy it someday i been to london
