Previously, any price you saw in US dollars, you just changed the currency sign to euro, and there was the final (Finnish) price after shipping, taxes and toll I wonder if it still applies... I guess so, since the conversion rate is still about the same (1 EUR = 1.4 USD or so), like earlier.
Jet City Amplification 100H. 739€ at Thomann, 572.86€ at Guitar Center. Thomann price without tax is 739 / 1.23 = 600.81€, which is more expensive than Guitar Center. But because of the Duty when you go to Check out you get this:
So it seems Thomann is still SLIGHTLY cheaper, but you can get different stuff there (like Heil microphones) AND Guitar Center does have this "Guaranteed lowest price" thing
