I've used the Amazon.com site and also DeepDiscount.com. The DeepDiscount order was $29.99 and wasn't taxed, the Amazon.com order was $34.77 and had import fees (edit: of $6.95, so ~20%), not an exact figure, but $30+
For security I'd only order from somewhere that accepts PayPal or a well known site such as Amazon.
