www.amazon.com
country: worldwide
shipping: methods can be chosen, such as priority mail, standard UPS, etc.
selection: selection is great for all genres of metal and music, but they sometimes list albums they end up not being able to find (especially imports). you can also find a "used" section for cheaper prices.
secure: yes
payment: paypal, credit/debit card.
comments: im sure everyone is familiar with amazon so i dont have to write too much, here. amazon.com is hit or miss. selection is pretty good, but they're slow as hell in their delivery (especially the xmas season) and they can be very, very expensive. use as a last resort if you can't find what youre looking for elsewhere. ive been waiting for over one month for 2 albums to arrive, and they still havent even been shipped, to this day.
