I would set , on my cart page, the default checkbox "shipping method" on Carrier method (instead "free shipping" that, in my case, means collection on site).
I see that Magento save free shipping on sales_flat_quote_address table when the customer create the shopping cart. How I can change this behavior with other shipping method?
I tried to change the "checked" attribute on phtml file, but is not sufficient (if the customer select "free shipping" and then leave from cart, add another product and return on checkout ... He see "carrier" checked).
