Well you can do what I did and ask your local ffl if they can order them. Or go to your local large volume S&W store.
My FFL ordered me some form his distributor. I ordered 8 and got them for $232 and change shipped. $29 mailed, taxed, and out the door. not shipped etc. they were a little under $28 a piece.
The local S&W shop had them for $38 a piece for those willing to payt he gotta have it now price.
Called S&W, and they said the best I could do ordering 8 mags was $32 each. I told them no thanks.
If you have a tax ID for resale, you can sign up with midway. I believe they charge $28 or so a pop plus shipping.
