The groupset is packed and shipped out now. The whole shipping, packaging etc. comes out to 47€. In addition to the 345€ i've paid so far i am at 392€ for the whole groupset. I could have optimized a little further by not shipping the whole packaging etc. but i didn't want the groupset to get damaged in transit.
I guess import taxes depend on luck and not included in this price, right? I bought mine on aliexpress, that after coupons(there is almost always a sale going on, now you can get it for 447 usd which is 409 eur)was 460$ which is 421 eur. A little bit more I guess, but thats fine(whether I will get taxes or not I don't know, the package is in europe but I have not received it yet). In my opinion 500 euros should be the price of the gex from the official store, otherwise as a new build it doesn't make sense to go with the gex for 600 euros when you can get an apex xplr groupset with a chain and cassette for 700 euros from bike-discount.de
