It can still be fun to visit flower shops in person, but who has time for that these days? Plus, are there really that many flower shops on street corners anymore? To sell flowers, you do have to have a brick and mortar business or green house somewhere, but these online shops probably have mega warehouses set up, wouldn’t you think?
That would likely be the case in Malaysia, just as I would expect where I live in the US.
Either way, those online shops seem to have it all these days. They have tons of flowers available, and they can make any arrangement you like. They will also have all kinds of choices without you even having to provide examples. Then you can pick and choose what you want, checking to see what discounts are available. You can imagine they will have all kinds of offers for special occasions, too.
