does anyone know where i can purchase instant camera's in kunming?

Hey there. You can access any instant camera you want from US online retailers. Most don't ship their product to China, but Dong-Xi.com does.

About Dong-Xi.com

Dong-Xi.com was created by China expats for China expats. All too often, our
friends have had a difficult time finding clothing that fits, locating favorite
name brands from back home and tired of spending hours traveling across the city
to shop. Our payment and shipping solutions allow you shop from US websites that
was otherwise impossible. www.dong-xi.com

Let me know if you have any specific questions.
