You are only required to pay a 50% deposit once you have seen and approved the pre-production sample and submitted your spreadsheet with your final order for mass production. We can provide an invoice with payment details. We accept cheque, EFT payments and credit card payments. We do not accept cash payments. If your school has a long payment cycle we can do an invoice for the 50% deposit based on an estimate and then for the balance payment we can adjust the amount to be the correct quantity.
