Price Factor

[farris12]

I'm selling paint, selling it per litre.

I sell 2,5, 5 and 10 litre cans.

My prices are per litre, ie:
2.5litre: $5 per litre
5 litre: $4.5 per litre
etc.

What I want on my product page:
A dropdown with the option to choose a can (2.5/5/10 litre)
So I selected Price by Attribute and I maked 3 attributes:
2.5
5
10

The 2.5 attribute has the following options:
Price: $5 (because it's $5 per litre)
Weight: 2.5
Price Factor: 2.5 (because it's 2.5 litre)

But, Zen calculates it wrong... I don't get $12.50 but something else (Tax included)

What am I doing wrong?

Here's a link:

additional info is on the product page

The Price Factor is used to compute the Product Price * Price Factor ... then if there are additional charges on the Attribute for an Attribute Price that is added in ...

If you also mark the Product as Priced by Attribute, you will get some really weird results ...

If you edit the Product and set the Product Price to 5.00 and mark it as Priced by Attribute NO ...

Then, go to the Attribute for the 2.5, then you will get:
Product Price + Product Price * Price Factor
5.00 + 5.00 * 2.5 = 17.50

If you include an Price Offset of 1.00 you will get:
5.00 + 5.00 * (2.5 - 1) = 12.50

Why do I have to make the price 5.0?

It's only $5 per litre when it's 2.5 litre...
It's $4.5 per litre when the costumer buys 5 litre, etc etc

How do I have to make that in ZC?

There are a number of ways to price this ...

Using the Price Factor, you need to set a Product Price ... otherwise, you cannot use the Price Factor ...

You could put the full price on the Attribute and then when they buy at the 2.5 liter they get the 2.5 liter price ...

It all depends on how you want the initial price to look ...

ok .

I think I can't use a fixed price, because of the fact that the pice depends on the # of liters...
So I think the best way is to doit with Attributes, isn't it?
But do I have to do something with the + or - in the attributes?

When there will be a new version of ZC (ever), they have to make this clearier...

[Ajeh]

On attributes, the + or blank is add to the Product Price (if any) and the - is subtract from it ...

[farris12]

I don't get it....

If I set a Product Price, I can't make qty discount (that's what it is, because for 2.5L you pay $5/L and for 5L you pay $4,5/L) because ZC is only working with the product price (and that's NOT $5 for 5L paint, but $4,5).

Everything that has to deal with 2.5L works by now, because that has to deal with the $5. But everything else then the 2.5L can doesn't work, because the price per liter gets lower when the costumer buys more...

It's very easy when I have my prices per can instead of per liter, but I haven't and calculating to 2.5L/5L etc is too much work if there is a option for it in ZC (if there isn't, then I have to )

[Ajeh]

Could you set the Product Price to the Price for 1 liter ...

Then set the Attribute for the 2.5 Liter to be:
Price Factor 2.5
Price Factor Offset 1.0

Price Factor 5
Price Factor Offset 1.0

etc. etc.

If you want to offer a discount on the number of liters, adjust the Price Factor and Price Factor Offset to obtain the right price ...


Otherwise, set the Product Price to 0.00 and set the Attribute Price to the correct amount for each of the sizes ...

If you then use Priced by Attribute, it will take that price as the displayed price ...

[farris12]

I've done what you were saying, but I still have the problem that ZC only deals with the 2.5L price....

These are my prices:

......................2.5L......5L.........10L
......................6.93/L....5.81/L....4.97/L
TOTAL incl TAX 19%:...20,62.....34.57.....59.14

But it doesn't work!! Only the price for 2.5L is right, that's because I've set the price to 6.93... But Price Factor 5 for 5L isn't working, because the price ISN'T 6.93/L but 5.81/L....

Hard problem :)

Is there anything stopping you from just saying on the Attribute itself the actual price instead of using the Price Factor?
