And it didn't give me any rough idea of shipping time, I just figured someone else would know a good indication of time from personal experience.

You should have received a shipping notification with a tracking code when your order was shipped march 11. The notification also says: "Shipping typically takes 2-5 days within Europe and 3-7 days to other destinations." This is based on the estimated shipping times provided by german post. Maybe that's a little optimistic, to the U.S. it sometimes takes only 7 days, but around 11-12 days seems more typical.
The shipping notification further says: "If goods do not arrive within two weeks and tracking status does not change, please contact support@nanoloop.com."

Normally, I ship orders at least 3 times a week, often the same day.
It happened a few times that I ran out of stock while travelling but did not close the shop on time so that I could ship orders only after I returned home. However, in those few cases where the delay is significantly longer than the "ships within 48h typical" stated on the shop site, I try to at least send out a notification with estimated shipping date.

USPS (and only USPS, other overseas destinations are fine) seemed to have some problems last year, with a few very long delays and even lost packages. No issues this year so far...

You're welcome.

it took two weeks in shipping. i remember that it was funny when it arrived, because the email said "if it takes longer than two weeks, notify me" and it got here right on time.

Oliver is a professional and takes care of his customers. You're better off dealing with him personally than asking us about it. I've never heard of anyone having a bad experience ordering from him.

This, of course, excludes not being able to because he is between production runs.
