Tarique,
When I managed a portrait artist, we ordered many frames from Abe Munn in New York. As a reseller of the frames, we got wholesale price and then made the profit off the markup. I think if you go to who makes the frame or a distributor, you'll get better deals. Going to a local retail shop is going to likely give you less discount because of their markup. But, if you go where the shops get their frames, you could pay less, though for less expensive frames, you might have to order a quantity. But, Munn's frames are each custom made and expensive and we were able to get wholesale price even ordering each one individually.
You can see Abe Munn and other framers on my Framers page:
