We use a weight based shipping structure. Different weight bands offer different carriers and there are upgrades available at each band. So currently we have an app config set to hide shipping prices with a value of $0.00. This how we keep from displaying shipping options that are not available at certain weights (e.g. First Class Mail on items weighing 2+lbs).
We now want to offer Free Shipping at the lowest priced option in each band. But doing so will hide that option under the current structure. And turning off the app config setting that hides items with zero shipping price will allow customers to select shipping options that aren't available for their item based on its weight.
Anyone know a way around this? I've considered charging .01 for the lowest shipping class at each weight, though it's technically not free. Can I put in a value of FREE instead of zero, or put in N/A or some other value for that will hide the shipping methods I don't want to display?
Thanks for any help.
