What do you charge for both of these? I am trying to figure out what the difference should be.. ie how much more to charge for the jumbo ones. Thanks!

The difference is usually 70%.

I charge $20 per doz or $2 ea. for reg size jumbo size is a flat $3.50 ea

The bakery where I worked for a while - regular sized were 99.cents each, the big ones $1.50 And I always thought we were undercharging.
