I buy from them quite often. For the most part I'm happy but I return what I'm not happy with. I have heard they give you problems if you return too much, I've never had that problem. They have good prices on jewelry, especially gold. But some of the jewelry I have ordered has been disappointing and I have returned it. It's not as good as it looks on TV or there is a clasp issue, etc.
The customer service is pretty good, not as good as it used to be but it's still the only shopping channel I would buy from.
