Happiness is an online store for kids and mums (and dads). For our test order (Play-Doh) they delivered the same day (within three hours, actually), so color us impressed.
Sri Lanka is seeing a lot of online stores coming up, which is a good thing. They tend to be for niche markets (alcohol, electronics, etc) and you can add kids items to that.
The Company
What really makes the difference to online ordering is the company behind it, ie, do they have authentic stuff, deliver it on time and have staff on hand to correct mess-ups. As far as we can tell, KTI - the company behind Happiness.lk - is the legit agent for Farlin, Kids Joy, Fisher Price, Mattel, LEGO, etc. They seem to be a stable offline business moving online, which is usually a reliable combination.
Happiness has physical stores in Bambalapitiya, Borella, Pelawatte, Negombo, Kandy, Kurunegala and Matara.
The Website
Happiness.lk is a solid site which seems to be running on a customized Magento platform. This probably means nothing to you, but it basically means that they're using an industry standard backend which is less prone to weirdness. You can find what you want by section (diapers, toys, maternity, clothes, etc) or by end user (baby, kids, moms). Alternately, you can also browse by brand.
