I buy at every price, basically. Since I'm a worker who earns a weekly income, I always try to spend around 20% of my earned income on precious metals as a form of savings. Since I buy each and every week, I don't tend to pay too much attention to the price. I do watch ratios of one thing to another and try to purchase whatever has the best ratio that week. A falling metals price and a strong USD is a great combination when you buy incrementally like this. I'll be getting a much larger pile for my dollars now.
