I have not yet installed Magento. however I am wondering if it offers this function, before I go through setting it up to find it doesn't. We need to ship items in one category by quantity. ie 1-15 shipping is $x, 16-20 it's $y and 21-30 it's $z. Then other categories would just use real time USPS or Fedex quotes.
Do youknow if it's possible to specify shipping method by category?
