Table Rates per Product vs Subtotal
Add a dropdown on the admin side of the Table Rate Extension, asking if the condition and rate should apply Per Product, or on the Subtotal of all items.
In other words, if I want shipping on my $50 items to be different than shipping on 2 x $25 items, I could set up conditions based on price, then select shipping to be calculated Per Product
I know a Per-Product extension exists, but then you couldn't offer different shipping options such as standard, expedited, overnight, international, etc.
This would basically give you the option to combine the best of both worlds.
Multiple shipping options per product! Really, I'm surprised there isn't already a way to do this.
