When we were in Bangkok, we saw one store with a poster that says we can send home what we buy from them. The store sells clothing items and some food stuff like tamarind and durian chips plus souvenir items. As per the owner of store, there are many foreigners who want to buy a lot of things but has the problem of bringing home because of the limited baggage allowance in the airport. Their service is both air cargo and ship cargo which is cheaper but understandably takes a longer time than air cargo. I think that is a good option they give to their customers.
