You have three options:
1. Leave as is. in your reports you will see number of conversions but not actual prices.
2. Change the variable to your average sale amount (you can also do this in the code wizard). this will just multiply the number of conversions by your average sale amount.
3. Use the shopping cart variable that corresponds to the order price. This will send the actual sale price to AdWords for reports.
I'm pretty sure with paypal you must be using paypal payflow integrated into your site to pass the actual variable; I don't think you can do it if you send users off your site and then they just return to your site after confirming the purchase at paypal (but not positive).
