Question

planning to go holiday in Bangkok this August or September but confuse about the actual Thailand grand sales ends at the end of August or September, please furnished me the actuall period of the sales, thanks

Answer 1

The Tourism authority state it as from 16 Jun till 15 Aug, so you need to plan to go early if you want to catch it. Available at all major stores and retailers. Not the open market though.

Answer 2

you can go check about the period of Bangkok Grand Sale at

http://www.tourismthailand.org/

But I dont think the market will be involved in the sales.
