It is very easy to compare the discounted rates on the different subscription levels, just follow these steps:
1. Create a free account ( no CC needed )
2. Log in to your account.
3. Enter all shipping information for the letter / package you want a rate for.
4. Instead of clicking the "show available rates" to get rates you click the little blue text below that
says "compare rates" , that will show a popup window with the rates for the available services and subscription level.
