Whenever you intend buying expensive technology online, you should be very careful from who and where you buy your audio gear. Some websites and suppliers are obviously respected, known as legitimate and not likely to scam you, but even places such as ebay where you have some protection against unscrupulous sellers can cause problems with rogue sellers, and independent websites can be scams. You can do some checks yourself, try to find previous customers from the company or by searching for them online. Additionally you can use a free reverse lookup website to try and find more about the seller.
