Hello All,
I know that I am not the only one that uses flat rate shipping through the USPS but I really like this software and would rather find something that will work then to change the software.
I am not a math whiz by any means and do not know how to go about making my shipping into a flat rate scale, % scale or to change it in any other way. So, here is my info as to the scale that I use for flat rate on my auctions and if you have any kind of scale made out that will be similar I would love to have the info on it:

USA:
1-6 items= 5.50
7-40 items= 10.00

Shipping to Canada:
1-6 items = 10.50
7-12 items= 21.00
up to 20 pounds = 24.65

Shipping Outside USA and Canada:
1-6 items = 12.50
7-12 items = 25.00
13 -18 items = 37.50
up to 20 pounds = 40.00

each item can be considered as a unit or equal to 1 pound.

thank you for any help or suggestions.
