stm, first time cloth diapering

♥MAMA❤ • 🕸SASSY🕸 Mummy of 2 Ghouls🦉🐁, Married on 🎃SAMHAIN👻forever in love💘 and 🖤eternally spooky🖤

We're due end of March and I want to cloth diapers but $30 for one diaper is crazy to me. where can I get cheap cloth diapers? and how many do we really need? I keep seeing "30!" everywhere. again ridiculous seeing as they need less every month. wish has some $2. I'm getting one to test the abilities of it on our toddler. I'd rather clean up pee then a poopsplosion at 3 am. lol any advice is violently appreciated. ps, not against using preforms and the little plu shell thing.
