Product pricing

Hi,
   Indeed you can.  See Page 191 of the V3 user guide - section on "Quantity Discounts".

If the FIXED bit is important (Only 1, 4 or 6 items) look at product options.
If you have a lot of these products it would be worth looking at the Apparel Add-on as that's all about easily managing a range of options for each product.
 

Hi John123,
  Oops - Of course, your correct, using Options is a-bad-idea  if your using stock levels in (or from) ProductCart, as the the software has no idea that there is a link between the text of the option selected and the quantity ordered.

When you say "with my existing website" - Are you using the/a  full ProductCart page, or have  you added code to your existing pages to add the products to the cart?

I assume you links are hard coded in that case.
Is the code your using based on the the  'Add to Cart from Anywhere' code from the Early Impact support pages? (I think  that's where it is anyway, perhaps the developers corner). From memory I believe it uses a small form including a quantity field.  You code put several versions on the page for the different quantities - with the quantity value pre-filled & hidden on each perhaps?

I was thinking that you should set up "Quantity Discounts" and then create individual links to the same product, but passing the quantity as part of the link.  If you set up 3 different products you would end up with a similar problem with inventory levels.

One thing to be aware of, is that when customers have gone to the cart pages there will be, on various pages, links, which may take them to other parts of the ProducCart side of your site, for example the "Contine Shopping" link on the cart page. Also, if you have a significant number of products, then managing all the links will potentially become time consuming and difficult. 

Hi,
   The Apparel Add-on is really suitable when you are selling products that have variations, such as size / color etc. Each variation is, in effect, a separate product with a separate SKU & stock level. For example, if it was rugs, you may have several different shapes/sizes and color variations, but you could show them all on a single page of your store.

From what I understand of your requirement the product your selling (in this case) is the same product, with just the quantity varying, so the versions should share the SKU and the stock level.

Can you give a link to the store and/or explain more about why you need the fixed variations in quantity? You can do so via PM if  you wish.
