Hi folks, I set up site for a client that wanted a flat rate shipping figure for all products in the cart. No problem here but now there is an entire section that has heavy stuff in it and I need to increase the flat rate shipping on these items only.

How can I sort this out. I don't have weight for items so I can't just use UPS or something to sort it out.
So, how can I change the shipping on about 10 specific items, or change it on an entire category.

thanks,
Nigel
