Quantity Discounts for 1.3

[tuncay]

hello
i didn't install the code yet but i have a question. what i want to do for my site is that for example: lets say somebody ordered $60worth of thing. they can choose a second item for $15 worth for free if they choose more then $15 for example $30 for the second item then i want it to reduce $15 off from $30 and charge the rest.

and i want some choices for example for a second choice if they order $100 then they can choose something worth $25.

is this module can do that or any other module ?

if it can i will try to install.

thank you in advance everybody for their hard work .

What you're asking for is not what this module does.

Hi, Swguy

Can your mod does following way of dicounting?

5% Discount on orders over £50

10% Discount on orders over £100

15% Discount on orders over £200

thanks!

[swguy]

Yes; discount by dollars spent was added in version 1.10.

Hi

thank you for the reply!

but this mod does not work if the website sells mix of both taxable and no-taxable products ? can you confirm it?

many thanks!

The restriction is you cannot recalculate tax (accurately) with a cart containing taxable and non-taxable items. You can use recalculate tax = no, and this is what many bricks & mortar retailers do.

Zen Cart does not break down the tax on an item by item basis, so it's impossible to reduce the tax on a mixed basket perfectly at the moment. Perhaps when the checkout rewrite is done, this issue will be addressed.

thank you for the explanation!

I am wondering what will happen if I use

zen cart's quantity discount on individual products + big dollar spending, on site sells mixed of taxable & non taxable items, and turn the "recaculate tax" off, what will happen? will result of reduction correctly inc tax?

many thanks!

I'm not absolutely positive what you're asking, but the logic that Big Spender uses to reduce tax is basically the same as the logic that Quantity Discounts uses. If you mix taxable and non-taxable items in the same basket and you're discounting with software I wrote, the only way you'll get a sensible number in all cases is to set recalculate tax to none and charge the full original amount of tax. In certain very specific cases for Quantity Discounts (but not Big Spender) you could write additional logic and get a close approximation in the manner that Group Pricing does; this is not something I support.

Like I said, when the checkout logic in Zen Cart is reworked so that taxes are available on a per item basis in the shopping cart object, I will update my code to provide more flexibility here, but until then this is a restriction.

thank you for reply!

It is pity your mod has such restriction under current version of zen cart, otherwise it will be extremely useful especially we are in recession now and shoppers like to see discount. let's hope future version of zen cart allows you to rewrite the mod.

once again, thank you very much for your help and time!

We have a variety of quantity discounts depending on the category. We have them set up and they work great but recently we had a customer that somehow went to a page that shows the default discount on the custom discounted category. They sent us a screenshot of the page and the interesting thing was that the cPath= in the url was for a category id that doesn't exist in our database.

So tested this an I can put any category id in the url and the product will still show up but the prolem is the discount text will display that category id's discount text or the default default.

So my problem is:

1. why does a product show up if the catergory id doesn't match
2. how can we ensure the customer sees the correct discount

Just to calrify when they go through the checkout process the correct discount is applied. We just have a problem of customer thinking we are giving them a raw deal becaue they see something different.
