how much would be the taxes from USA to europe(italy) if I buy SP-CMC-4 or 8 + SP-SPSB-6 from SoundPro site?
I've got to pay taxes also if I buy an used JB3 from a user of this forum in the yard sale?
buy the JB3 this side of europe, no import to worry about. You can get good refurbs or used JB3's on ebay for about £90, sometimes with the battery.
try and pick up your mics in the yard sale
1. they will be slightly cheaper than from SP;
2. you may be able to ask the seller to put just $50/gift on the customs form, therefore you will pay no import duty. Alternatively if you have a good friend in the states they could buy them for you and send them to you labelled as a gift.
SP have over-insured a package and put it on the custom form on an order I made, so I once paid £30 import on a $20 cable
I usually expect about a 50% duty on packages from the states.
