Traditional e-commerce is absolutely ubiquitous in SEA. Their primary e-commerce channels are web-page and app-based shopping carts, just like we have in the west. While it’s typical to support local payment methods, most sales are processed via credit/debit cards, just like in the west. Non-traditional channels certainly exist, but they are absolutely a fringe channel. Tupperware Parties are still a thing in SEA (although they’re mostly for MLM products), and a lot of businesses will let you order via DM, but those sales are nothing compared to the volume on sites like Shopee, Lazada, Tokopedia... They caught on a bit later than the west (I was personally involved in one of the first major e-commerce sites in a particular SEA economy), but their growing middle class does online shopping pretty much exactly the same way we do.
