Can you use a debit card for monthly payments?

I only have a debit card and am looking to purchase a nikon D5100. At the moment I do not have the money but have a continuous source of income. Is this possible and if so where would I need to buy it from?
(Yes, I'm under 18 but unlike the rest of the teenage population I'm responsible, self motivated, and self punishing. Do not be ignorant by telling me that I'm to young for a debit card or to make extraneous purchases.)

If it has a Visa or Mastercard logo you can use it.

A debit card is not a credit card. Only credit cards let you make monthly installments on your purchases.

A debit card is just a charge card linked to a checking account. You must have the funds in the checking account to cover this purchase. If not, you will be hit with a ton of fees.
