You want a reputable dealer. Nothing is guaranteed. Which is why you want a reputable dealer. Prices are competitive between the main dealers. Keep a close eye on premiums, shipping, and other fees. Depending on your location, what you are buying, and from who, shipping costs, etc, can make a big difference in price. Different dealers charge different premiums. Some have fees that other dealers do not have. Beware customs duties, taxes, etc. Remember, metal is heavy. It usually has to be insured if you ship it. Crossing borders can also be an issue. Sometimes I can save a lot just by driving to the nearest physical dealer to buy in person.
