Some noteworthy changes in USPS policies – they don’t offer tracking for registered mail since this year’s October. As this is the standart shipping option for most of my clients, I just wanted to let you know. The tracking works until the parcel leaves Latvia and that is the last tracking information you will get.

Express Mail Service still has tracking available, so, if unsure, please choose that to ensure you can trace your parcel and get it as soon as possible.
I will be updating my shipping policies and I might cut registered shipping option off completely, but not just yet as the overall service seems to be as before, aside from the lack on shipping information.
