Shipping problem - Per Weight Unit

[jman2007]

Just started using Zen Cart but I have a problem with the shipping module. I can't seem to find the answer in this forum for my problem. If you do please post link. Thank you..

I have two different items that I need to ship. Zones is not applicable.
item A cost $5.00 + $1.00 additional item A to be shipped.
item B cost $10.00 + $5.00 additional item B to be shipped.

Therefore, if a customer purchase one item A, shipping is just $5.00 but any additional purchase of item A I have to charge $1.00 per item A. If a customer purchase one item B, shipping is just $10.00 but additional purchase of item B I have to charge $5.00 per item B.

I was able to input 1 for shipping weight, shipping cost per unit to 1, and handling fee $4.00 which equals $5.00. If another item A is added to be purchased this Per Weight Unit module will keep adding a $1.00 per item A. This works fine for item A but I am trying to figure out how to calculate item B.

Can anybody help?

What happens if I order 2 "A"s and 3 "B"s?

[jman2007]

$5.00 (1st item A) + $1.00 (2nd item A) = $6.00
$10.00 (1st item B) + $5.00 (2nd item B) + $5.00 (3rd item B) = $20.00
Therefore $6.00 + $20.00 = $26.00 shipping cost.

Sorry Kim... That is how I want it to calculate but it is not doing that..

Can anybody help me find a solution to this problem? I am able to set my shipping rate for item A but how do I set item B. If I set item B's shipping weight to 6, shipping cost per unit to 1, and handling fee to 4.00 which total to $10.00 shipping cost for one item B. But when a customer wants to buy another item B the calculations is different. (One item B is $6.00 * 2 items * 1) + handling ($4.00) equals $16.00 for shipping cost. I want it $15.00 not $16.00. Because I am shipping two items, I have to charge the first item B $10.00, the second item B $5.00. Any additional item B I charge another $5.00, etc..they are all add together...
