additional charges via attribute

[gsdcypher]

hi all,

how or what is the best way to set up additional charges to the base price based on quantity (of the same item) via attributes.

for example:

1 pair of shoes, 2 pairs of the same shoes, 3 pairs of the same shoes...

shoes = 40.00

1 item = +3.00, so (40.00 + 3.00 = 43.00)
2 items = +1.50, so (80.00 + 3.00 + 1.50 = 84.50)
3 items = .75, so (120.00 + 3.00 + 1.50 + .75 = 125.25)

You sure you don't rather want to use QUANTITY DISCOUNTS feature?

Why do you want to do this using attributes?

PS: You may have a very good reason... but this is best achieved using Quantity Discounts...
