It seems that many of our customers are not smart enough to figure this out so we have to make the "Ship to different address" option default (checked - the radio button). This is in STEP 1 of the Checkout (1 BILLING INFORMATION)
What is the best way to do that? Thanks for any suggestions! :-*
Edited on June 1st, 2018:
I have implemented the solution below and it worked great.
Now, however, all of sudden - it reverts back to "Ship to this address" again. I went into the billing.phtml file in
and the code is still the correct one (the changed one). Would anyone know why this just stopped working all of a sudden by itself? (the file was not overwritten)
