I don't use formula but a lot of mom's in my facebook mom groups I see either posting asking for coupons or giving them away for free. I always get the $5 checks for Enfamil and similac and send them to people when I see them asking for them.

Defiantly the target up and up brand I would switch to that normally

i have wic thwy only give me 7 can a month mu son go through 1 can in 2 to 3 days

you can use the store brands like targets up & up.. they're the exact same thing. Like a can of similac is like $16 and the store tin is $13. Maybe call ur doctor or local wic and ask if they have available samples?

I don't know about formula since my first son was on the super expensive stuff, and my second kiddo is breastfed, but if baby doesn't have allergies you can try getting donor milk until you can afford formula.

the store brand of formula is usually cheaper...we used the up and up from target big can was the same price as a small can of the regular stuff

Have you tried WIC?
