You might wanna check this thread: Waiting for EU sales or importing?
There are a couple of folks who have successfully been using a freight forwarder. I’m current waiting for my package to arrive at MyUS’s US facility in order to then be shipped across the Atlantic.
If you order now (like: today) there should be a fair chance you can hold your package in your hands before the 31st. If you’re not a business owner, you can have the freight fowarder pay the import duties and taxes (usually import VAT) beforehand which may slightly speed up customs handling. MyUS hands out referral links with 20% off your first shipment for new users, feel free to PM me if you’re interested.
This is what it shows for the dimensions and weight of my package (DYI, w/RAM, SSD, 5 expansion modules, no charger): 5,5 lbs / 2,49 kg, 18x11x8 inches.
PS: Stackry might indeed be an interesting choice since their warehouse in NH is rather close to Framework’s fulfillment center in NJ, so one would assume it’ll get there faster.
