Have discovered that postal rates can vary from 3 Bht per letter to 80 Bht (Registered,EMS.....). My Thai-neighbors usually go by a 10 Bht stamp, but complain "sometimes not so good" and none of them can tell me of the time frame a 10 Bht letter should reach it's destiny.

As a Farang, what postage price range do you use for inland-mail to avoid the "sometimes not so good" syndrome?

Or is it better to go by EMS/Registered in the first place and forget about the rest?

Cheers.

Personally I always use 'registered' or the EMS, both are trackable and always arrive.

When in doubt, as the Thai Post office, their www site is pretty good:
