A lot of the name brands have different price range/quality ammo.
Winchester, for example, has a lower end 'white box' that is less expensive then their top of the line ammo.
I reload almost everything I shoot, especially at todays prices, but, for my carry pistol, for example, I might get a 20 round box of the high end stuff, and practice with the cheaper offerings, or my reloads.
IMHO, if you don't reload, get the cheap stuff for plinking/practice and the good stuff for the real deal.
You still need to shoot the premium ammo, on occasion, to get used to it and where it shoots, in your firearm.
