I purchase my own carry ammo at a local cop shop and the price is fair,but if you are looking for practice ammo why don't you try reloading? Ive been reloading for years and am glad I don't have to pay top prices for plinking ammo,plus you can taylor your ammo to your gun if you like,load up ball,wadcutter,hollow point,etc. It is a lot of fun if you are a shooter to begin with and it doesn't have to be a big expense just to start up,you can get start up kits from lee or others for a reasonable price.Just remember you probalbly can NOT carry your reloads on or off duty,stick to factory ammo for work, it's a liability thing and can get you in some hot water in court,just imagine a defence lawyer making wild claims of you making "deadlier ammo",so only use your reloads for practice.
