Shopping cart doubling price of products priced by attributes

[kobra]

But each product is priced differently, so I can't assign a price to the attribute, otherwise I would have to do that 500 times

500 times??? you only indicated

4, 8, & 16 oz = three

A "factor" is math = if all priced differently what and how can this be calculated mathematically?

Sorry, I must be messing up my communication - my apologies.

I have 500 skus with 500 different prices. I am using the 4oz pricing as the "base price" for the unit since that is the smallest quantity people can buy. So there are 500 different 4oz prices, but the 4oz factor is always the base price of the item times(x) 1.0

So, sku #1 has a base price of $2.00 and therefore the 4oz attribute price is base price x 1.0 = $2.00. Sku #2 has a base price of $3.50 and therefore the 4oz price is $3.50.

Then, the 8oz version is the base price of each item x 2.0. For sku # 1, this is $4.00, but for sku #2 this is $7.00.

And so on.

The funny thing is that this is all calculating fine - the attributes are showing up priced at the right amounts. It is just that when I put them into the shopping cart, they are adding again.

Does that make more sense?

OK....

If ALL of your items are based upon the entered price, then that X2 for 8oz, and X4 for 16oz then this is the math of the attributes controller:

Base Price - Plus (Base X Factor) - minus (Base X Offset)

So using this you enter the 4oz price when you create the product

You create 1 attribute name, Size or Amount, or???
Then 3 attribute values 4oz, 8oz, 16oz

Add these to a product as

4oz - -enter factor of 1 and offset of 1
8oz - -enter factor of 2 and offset of 1
16oz - -enter factor of 4 and offset of 1

Yes, that is great because that makes the cart work. Except in the product screen it only shows the base price plus the add-on amounts, not the total prices of the products for each version. I was hoping that when priced by attributes, the attributes total price would show in the product screen. Like this:

Sku #1
base price $2.00

4oz (default checked) $2.00
8oz $4.00
16 oz $8.00

Instead of this:

Sku #1
base price $2.00

4oz (+0)
8oz (+2.00)
16oz (+6.00)

I think that is confusing for the customer to have to do the math before they click on add to cart.

Is there no way to do this with my configuration of the attributes?

[kobra]

Yes, but you did not want to do it 500 times

You either invest the time and get it so it is easy for your customers

Or do it this way and make them do the math

Ok, sigh, thank you so very much! At least you have helped me exhaust all options. I wish in later versions of zencart there was a way to handle large numbers of different items with the same price factors for the attributes, and where we could list the total item price.

I particularly thank you for your patience in helping me through this!

Kind regards,

Kelly
