all come from the same manufacturer
but different packaging to be sold in different countries
order in bulk, ship in bulk
economies of scale
tts why can be cheap
But in terms of bulk, is definitely NTUC Fair Price.. Why dont
they adapt the lower selling price to gain more customers? Their
price difference can be 30-60% or even 100% sometimes.. The reason
must not be so simple.. just order in bulk, pay cash, ship in bulk,
employ less and cheaper worker, cut cost, less air-con... price
difference is too huge.. and they are making money.. (I assumed,
because they are opening more outlets..)
