The Secondhand School Shop sells secondary school products in good condition at approximately 2/3 of the current retail price. That selling price is then split equally between the seller and the store.
This means
Buyer Savings 1/3 approximately
Seller Refunds 1/3 approximately
Store Commissions 1/3 approximately
Refunds can be taken as store credit or via cheque.
Unsold items are retained while they remain current and are then donated to Rotary for developing countries.
