The coffee beans and Matcha Powder, etc. they using probably is those Starbucks-kind one.
Think they got no economies of scale to offer cheaper than those chain stalls.
After all these kind of beveragee require all those equipments and tools, etc.
Unless you want them to sell normal kopi like those coffee shops kind, then will be cheaper. Since just brew the beans and just pour via the sock.
Think the customers they have, too little to recover back on the equipment and tools, etc. + the maintenance ba. After all, HDB so small.
Those landed properties home-cafes probably sell abit cheaper, because they got enough space to accommodate more customers.
