finally I choose using agent instead, since they can help repack and slightly (very little, at least) cheaper on shipping fees

I'm yiton service, quite responsive, help to repack stuff to avoid higher shipping fees BIG BIG

I'm not a frequent shopper at Taobao. But from my experience tell buying directly from Taobao are expected for higher shipping (either consolidate or direct shipping) if you bought more items. From agent shipping fee are relatively lower , but the currency might be mark-up a bit (it doesn't matter for me).

送关should means that the item is at the Malyasia Customs. Depends on our customs efficiency to see how long it will get cleared. Based on my experience it may take from less than a day up to 5 working days depending on your luck or their work load.
