A woocommerce plugin that allows partial payments. People pay a certain % of the product and they get it reserved, till they come back to pay the rest. If they don´t pay the rest, the deposit gets automatically cancelled. You can even get some products fully and some others with a deposit at the same time.
Knowing how much some guys love split payments, it may work. Only I imagine you need some scarcity to make it work.
