I bought a variety of silver bars and coins on Dec 22nd at $18.00 when the price dropped that day. I just got a call they can't deliver the 9 kilo bars that made up part of my order and I have to substitute 10 oz bars, 5 oz or 1 oz coins. They also had no 50 oz bars available. They said that the kilo bars are back ordered for 2 months and no date on 50 oz bar availability. I find it odd that the larger sizes are not available but smaller are and suspect something is up with silver because larger sizes use up silver faster and they may be having supply issues.
