Yes. When you buy from co:sim through our links, co:sim pays us a commission, and we give 50% of it to the charity or club you choose. We pay each cause its confirmed commission every quarter (Jan, Apr, Jul, Oct), once the store has confirmed the sale, usually 30 to 90 days after the order.

Does using Promo Magpie cost more?
