In the EDMW thread discussion on this, it was opined that the seller is either fucking dumb (to accept such a large order without advance payment or at least downpayment) or fucking smart (to orchestrate the entire fiasco 自导自演 for publicity's sake and to drum up business, betting that kind Singaporeans hearing his plight on social media would buy up the 150 packs, where he normally wouldn't be able to sell so many in one day).
