First, I get prompt, courteous and knowledgeable replies to my questions, and I really like being able to communicate via secure notifications rather than discuss transactions over unsecure e-mail.
Second, I am impressed by how convenient and smooth Silver Bullion makes it for customers to pay: I just renewed my storage (by the way, the fees are VERY competitive), I paid my transfer-in order, now I paid for the storage extension with a debit card, there were NO problems, I paid in USD.
Third, I want to compliment your team, the website is very well laid out, lots of info is available, and customer service is excellent!
