Not unexpected, but still unfortunate. I miss the days when I was trading scale model kits with a couple internet acquaintances in the UK, I could send two kits for $10-$15 total without any customs fee's. Now the same box would cost me $50-75 to send plus all the duty and tariff and whatnot.
I'll have to look into the IOSS platform. On the surface it sure sounds easier than the UK requirement of establishing a full sales tax account and having to do regular financial disclosures. It also looks like people using UPS and similar services really won't see as much of an impact, mainly just collecting the VAT from the customer and paying it through to UPS. Only guys like me who use the postal service currently with have a drastic change.
On the flip side, now that Marco carries nearly all of my stuff (albeit at a higher pricing than myself) I may just transition all my EU sales over to Marco starting on July 1st. This was my original plan anyway.
