Deals from outside Europe are not an issue here... As long as we can be specific about a final price, with both taxes (and change) and shipping included, to an European buyer.
That's not quite how things work, sadly. The final price is a Great Unknown because there are customs/import fees as well, and they depend on many, many things - the country itself, the company which brings it over, the guy working at customs service who may have gotten up on their left foot today, the original price and the original price bracket, etc.
Here's a silly example from Amazon US, a WiiM Amp, and it also estimates import fees because it can't know for sure:
$299.00
$183.65 Shipping & Import Fees
(of which)
Estimated Import Fees Deposit $96.53
I have been on the receiving end of a "wrong" company doing customs clearance. Ordered the same item twice from Ukraine (wanted to help a bit), it was a gimmick with a price of 15-ish €. First time the customs/import clearance and fees were dealt with by our national postal service and I paid about 10€. The second time it ended up with a different private company and I paid about 55€ because they ran it through xray, opened the package, tested for drugs, involved a courier back and forth while doing so, etc.
Sometimes a customs guy doing customs things will let a package through and calculate things based on what the price sticker says, sometimes they'll use their own price estimation tables, sometimes they will ask for an original receipt and bill the time spent on doing that, sometimes you have to pay for the package spending over x days in customs processing...........
Basically unless you're seriously desperate about an item, you do NOT order from outside EU, because that's a financial disaster in the making.
