Mmmmh, as you may know I live in Argentina, and if I use FLAT RATE ENVELOPES I NEVER pay a cent to get my fabrics. The Postman just requires my signature (or sb else's as I have my orders delivered at my job)and my fabrics ARE ON MY HAND AT THE VERY MOMENT.
But I do know by experience, that ALL packages that come with tracking and/or insurance are held at customs.
And must pay for taxes.
That's why I never ever have my orders shipped in box.
Unfortunately have had a recent problem with a well-known on-line store, who ignored my request. But that's for another thread I guess.
Hope this info is useful.
