Brownell's discount varies heavily from item to item. They generally don't discount gunsmithing tools at all, with some exceptions, which I can only think are mistakes. For example, the DPMS Multi-Tool retails for $33.95, dealer price is $19.95. The Smith Enterprises tool, which is pretty much the exact same thing retails for $36.70, and there is no dealer discount.
If you have a catalog, the dealer price is coded in. For example, the line listing the price for the aforementioned DPMS tool is:
#231-000-007 AR-15 Multi-Tool 1C19D95......$33.95
The bolds were added by me, but represent the dealer price. The above discount, is pretty deep. Most stuff isn't discounted that much. However, you'll note there are plenty of other places that sell the tool for much closer to the "dealer" price of $20 than Brownell's $34 normal price. Other stuff is hardly discounted at all.
However, I find that I actually get a better end price from Midway. The actual % discount from Brownell's is more, but Midway's "normal" price is often much less. For example (and somewhat ironic), I can get Brownell's Acraglas cheaper from Midway than direct from Brownell's. It seems like Brownell's is aimed more at dealer sales and Midway to "regular" folks. Brownell's "normal" prices are sort of like "manufacture's suggested retail" prices, Midway's "normal" prices are more along the lines of what you'd normally expect to pay at a store (i.e., less that MSRP), and the dealer price could go either way.
Good thing about Brownell's is they have flat rate shipping ($6.95, unless they've increased it lately), including backorders. Midway charged shipping based on weight, but it is not outrageous. They also charge each backorder shipment as if it was a separate order, so shipping will be higher if your order ends up going out in multiple shipments. However, Brownell's does not offer online inventory status, whereas Midway does, so you know if there are going to be backorders beforehand. I've placed more than one order at Brownell's really only needing one thing, but ordering multiple items because of the flat rate shipping, and end up having the thing I really needed backordered. Brownell's also carries a larger number of products, but Midway is pretty rapidly expanding their line.
