there are many factors when buying and shipping amps. Before you even think about it, check the voltage and frequency in your country. If you buy an amp from america and it doesn't work in your plugs, then you have wasted alot of money.

If you are sure you're going to do it then email the shop before and ask for prices.

i would suggest www.coda-music.com it's an english based company and has good prices
