perweightunit Shipping Module, different shipping prices for different quantities

[kelley777]

Hi, Hope everyone is having a beautiful night! I am trying to figure out the perweightunit shipping module, in order to offer different shipping fees for different quantities of a product purchased. Example: Product 1 costs $5.88 to ship, but if a customer orders 2 of that same product, it will only cost $7.45. If they order 3, it will cost $7.93, etc. until someone orders 20, then shipping if free. (I am really not wanting to sign up with the USPS to use their quote module thingy.) If anyone could point me in the right direction, or even explain this, that would be awesome! Thanks, Kelley
