As in the real world Micro money may either be spent or saved. The Micro Store is one of several places citizens of the MicroVillage are able to spend their money. The store is stocked with donations from business partners. The MicroVillage PTA also provides funding for Micro Store merchandise. The store carries more than four hundred regular items and has more than one hundred special sale items.
Students are able to purchase everything from pencils and paper to science kits.
On special occasions the store has special event sales. Sales at Christmas and Valentine's Day bring outside customers into the school to purchase items. Being able to spend Micro money on real world items makes the monetary system work and gives the currency real value. Students are faced with decisions about whether to spend or save money, what to spend money on, and how to secure money. Placing students into a real world situation is one principle of the Micro Society concept.
