Well, by doing exactly what you just did,,You come in here and ask what other members know about the particular supplier in question..Ask what they know and how their experience in dealing with the particular supplier was...
Then wait a day or so and you will get specific answers about that supplier...
As far as rightwholesale, I myself have not had any dealings with them but they have had excellent reviews from other members in here.
I have only seen good experiences by other members who have spoken about them....
