Buying formula

So I started my son on formula (similac pro advance). We have wic and we’ll get about seven cans because he’s almost eight months. Wic will give us about 12oz cans and we might have to buy a big can. We have to go a cheaper route though as money is pretty tight

Is parents choice advantage infant formula similar to similac adavnce or pro advance ?

Sorry if this seems dumb but I’m still learning as a first time mom.
