The price of a disposable camera depends on a few different variables. Generally, you can expect to pay between $10 and $25. Buying them at drug stores typically makes them more expensive. Versions with high-sensitivity film often cost more than lower ISO models. Stepping up to waterproof models will also typically raise the price since you're paying for an extra-strong plastic case. Once you consider the purchase price, remember that you'll have to get those photos developed, too, which will typically cost as much as the camera itself, if not more.
