Online Shopping from Foreign Online Stores

Hola dear expats and locals,

I am new to the forum as well as to Colombo. However, I have been here long enough to realize that I am missing some western products from my daily routine, so I was thinking of purchasing them online and having them shipped to Colombo.

Could you please share you knowledge and experience of how online shopping in foreign stores and delivery to Sri Lanka works?

I already got the sense that the customs in SL has quite strict regulations, so I want to make sure that I know what I would get into if I decide to import. So, have you had any trouble with customs? What are the limits in quantity and price? What are the taxes if any? Etc.

Btw, the items I am mainly interested in purchasing are cosmetics (bath products, face care and make-up) and clothes + accessories (shoes, bags, etc.). And the stores I'd get them from are those like Asos, Harrods, Nordstrom, etc.

Thank you all in advance and I look forward to your replies!

Cheers!
