Re: Cheap 357 or 38 amo!
While I hate to give this advice, try Walmart for Winchester white box. It is new ammo and reasonable. Before you do, go to your local gun shop and look for 38spl. reloads. There's lots of brands out there and they usually sell for $6-8 dollars for a box of 50. This is usually great stuff for plinking.
The best things in life, are not things.
