In my state, and with my insurance, I asked at the pharmacy and she told me to go take one off the shelf of the store (target) and bring it back to the pharmacy. She didn't show me the list of allowed brands and types but it could be manual or electric, don't have to be a working mom, there was no co-pay, and she didn't mention a price limit. If there are none on the shelf you just have to come back when they are in stock.
I provided my ID and insurance card, the name of my midwife and my contact info.
She told me to come back in 15 minutes (just like filling a prescription) and it was all done. Walked out with a free pump and I'm super stoked!
