I didn't see a thread on this previously, and I dont think this violates the rules at all:

How do store (LHS) prices in Japan, S.Korea, or China compare to the U.S., U.K., etc in regards to electronics? Non-web site sales.

In other words, is there a significant price difference between buying a Futaba 4px in a store in Tokyo vs. Dallas, TX?

If I happened to find myself in Hong Kong or Seoul on business should I load up on electronics?

Depending on the item being looked at, 10-30% less in the norm in HK; dunno about Korea/Japan. Be aware though that on many items, the U.S. importer won't honor the warranty on "imported" ones, even if it was you personally importing it - Futaba is one of those known to be that way. Thus, the $400 4PX in HK is a $400 no-warranty one whereas the $440 (after coupon) one from Tower is easily returned/repaired if there is an issue.

I wouldn't be bringing the "empty suitcase" in other words. Great for a hard to find in the U.S. Tamiya part, even better for drifting car parts not otherwise imported here, not the real bargain hunters paradise you might imagine it to be.

Thanks,
I've seen the massive differential in prices in Seoul regarding computer parts - also familiar with warranty/knockoff situations. Didn't know if RC electronics had the same market or not.
