R4 Pixar Set is US 74 shipped to Taiwan
The Set is too expensive consider:

A: R1 Toy Story 2 is $16 shipped to Taiwan
B: R1 Toy Story / Toy Story 2 is $30 shipped to Taiwan
C: R1 Pixar 15th anniversary set is $ 40 shipped to Taiwan

So it depends on what you already have, and are you happy with them.

If you are happy with your Toy Story and A Bug's Life, get A
If you are happy with your A Bug's Life and want Toy Story and Toy Story 2, get B

The reason I do not recommend C at all is R1 A Bug's Life CE is being re-released in May this year. Many people want to get that one. If you are one of them, get B then. Sell your R1 A Bug's Life gold collection and get R1 A Bug's Life CE in the future
