hi ajeh,

i was looking at something similar for items that cost over the standard table rate for shipping. but the additional cost is not the same for item multiples.
for example the first item additional shipping cost is 3.00, adding another of the same item is an additional cost of 1.00 to shipping.

item 1 standard rate 8.00 (1 x 8.00 + 3.00), (2 x 8.00 + 1.00)

item 2 standard rate 8.00 (1 x 8.00 + 4.00), (2 x 8.00 + 1.50)

item 3 standard rate 10.00 (1 x 10.00 +3.00), (2 x 10.00 + 2.00)

so for item 3, it's the standard table rate +3.00 for the first and +2.00 for the second.

any ideas???
