Okay, so I recently placed on order with a Romanian supplier (my first order with this source). The package was shipped quickly and I received the parcel within 10 days. I checked the tracking info daily on USPS and noticed that the parcel was quickly cleared through customs. Yesterday, however, I received a notice from USPS saying that they had "missed" me at home and that I needed to go pick up the package. I was a bit concerned since there was no signature confirmation requirement, but I researched a bit and it seems this is not entirely out of the ordinary. I picked up the package today without incident, but I noticed that there was a sticker on the package saying "Inbound International Parcel, Signature Required" with a Customs label. The lady at the post office had me sign and also write my address. I didn't really want to, but I was already there and I didn't want to just walk out, ya know? So now I'm a bit worried, the order was only for a couple of bottles of test, but I've got some other gear at home and I'm worried customs is going to come knocking on my door. Thoughts?
