They are way way better priced than the big bullion dealers and they're a small business. I can personally vouch for them. I've made a dozen order through them.

My Litecoin comparison to BTC was an analogy of silver to gold. Silver is a production commodity akin to oil. We consume a lot of silver.

Silver is very very different.
