Change Default Radio – wpsc-simple-shipping

For this site: https://designinreallife.com/

I’m using:
Flat Rate (Ground Shipping) via wpsc e-commerce
Fixed Rage (Local Pickup) via wpsc-simple-shipping

If I go to my shopping cart checkout page the radio button for “Fixed Rate” (my Local Pickup Option) is activated by default.

I want to have the radio button for “Flat Rate” to be activated so that people buying in other parts of the country aren’t defaulting to my $0.00 shipping for local pickup.

Been wracking my brain trying to make this fix, and I haven’t solved it yet. For all my input types=”radio” within my php docs, I’ve removed “checked”. But this hasn’t affected this default that I can’t seem to locate.

Also, an acceptable fix would be to have no radios selected by default.

Any insight? Anyone? Please?
Thank you!
