Nestle involvement - for reference :
The global coffee alliance since 2018
The purchase included Starbucks®, Seattle's Best Coffee®, Starbucks Reserve®, Teavana™, Starbucks VIA® and Torrefazione Italia® and the distribution deal cost Nestlé $7.15 billion for the exclusive right to market, sell and distribute Starbucks products. (Google)
So it is possible your rip off priced cup of "Hi So" coffee could be simply Nescafe??
When I lived in Thailand, I used Amazon coffee shops.
