There are a lot of “redirect and transportation” services available. I have no idea what country you are located but there are special services for a lot of countries.
For example i’am located in Bulgaria, but a lot of english and german merchants don’t ship/deliver to Bulgaria and/or have realy high delivery costs. For such cases i use such such parcel/mail/postage forward/redirect/transport services which are realy cheap. In my case you get an ID + the adress of the redirect/forward service, means my real adress is hidden (name not as i have to pay somehow!), but in your case and payment with ZEC that’s not an issue.
I remember as well that at some time and many years ago i had a post adress in London/UK for an offshore company at the Seychelles which has cost 20 GBR + forward postage for each letter/parcel. But i doubt you need an instant mail adress somewhere.
Try google with the following keywords: Your country, redirect, forward, postage, parcel, sender country
