Suppose you went shopping for a toy to give a younger sibling for their birthday. You purchased a toy at a large retail chain, like Walmart or Target.

When you arrived to the store, you found several aisles filled with toys available for purchase. You did not order the toy ahead of time $($over the phone, online, etc.$),$ and the toy was completely made and ready for purchase when you bought it from the store.

Are the types of toys being sold at these large retail chains part of a push system, a pull system, or a system that is a mix of push and pull?
