Shipping an item to HK from a store that only sells/ ships within the US.

Hi everyone, I had a question. So I really want to get something that is only available in mercari (forgive my lack of spelling skills).

Unfortunately, that store only ships within US or Canada, and I do not know anyone that lives there/ can help.

I wanted to ask how you fellow Hong Kongers ship items that are only restricted to US/ Canada?

I have googled shipnbuy but I wanted to hear your thoughts as it seems to have mixed reviews and I'm scared.
