Has anyone in the US ordered from CousinsUK in the last month? How long did the shipment take (also which service option you used would be appreciated)?
I need a mainspring size only they currently have, but I'm thinking of doing a large order if the shipment doesn't take a month to get here.
My last experience was before the pandemic and a mainspring and screwdriver in a Royal Mail bubble mailer took a week. I'm on the east coast of the US.
There are no fees and no paperwork to receive items up to USD800 in the US from abroad.

And even if the value is higher than that, CBP does not worry much about duty fees which in most cases are minimal anyway but they care about what the item is and if it complies with regulations. A simple leather watch strap may cause a a package to be inspected and cause much further complications.
