Crowd Control can only function with flat-rate shipping fees and cannot work with carrier calculated rates. Our system must be able to subtract a known shipping value from a cart total. You can have shipping rates that are based on cost and/or weight, but they must be a fixed rate.

Example:

$10 US Shipping up to 2 lbs

$15 US Shipping over 2 lbs

Free Shipping on orders over $100

Applicable shipping rates should not be changed while using Crowd Control.

To charge more precise shipping fees for add-ons, consider giving reward items a weight of 0 lbs/kgs and use a weight-based shipping rate of $0 for items with no weight.
