Been using CSC for many years but never addressed this.
Right now I ship most everything FedEx or USPS but I have a line of products in the store that I want to specifiy flat rate shipping.. simple enough I guess, however, I do NOT want to show any other shipping options at checkout.
If it's $50 to ship something then we bypass everything else and boom... if shows $50 shipping in the cart.. have a nice day.
I already have a free shipping method for store pickups, etc and I don't want to confuse customers.. just make it real simple.
Now.. you may ask why I don't just figure it in to the price... because it skewers the pricing in search engines, etc. I want to keep this as simple and straight forward as possible.
I'm on the latest greatest CSC.
