Help with product payment options

I've put together a camp store to support our scholarship fund for camp. Is there a way to give two options for payment - both via paypal and via mailed check - without having to essentially create duplicate options of everything on the same page?

Unfortunately, it's not possible to add more than one payment integration to the same form. Now, what you can do is to set up your products using basic fields and manually perform the calculations to get the total. 

Once you get the total you may ask the user if they want to pay using either PayPal or check, if they select PayPal you may then pass the total to PayPal and redirect them to the payment page, if they select check you may show them the instructions about how to send the payment. 

These guides will help you performing calculations and passing the calculated amount to the PayPal payment field:

Note that if you have already configured products through the payment wizard, you will need to get rid of that and configure them using basic fields (dropdowns, check boxes, radio buttons, text boxes).
