Unless you're buying 10,000 shares at a time, your purchase will not effect the price. A 10,000 share buy will only raise it 1/8th of a point. And houses who do this to their customers get censured. Usually by losing the business for a few months. Beyond that comes the SEC who do not take kindly to such practices.

I vow to stick with silver....even junk silver. I hold it in my hand, and either way- I still own it no matter what the deal was.
