Member and quantity discount pricing

Forgive me if this has been answered before...

I have a zencart installation for a non-profit association (www.iands.org). The cart is used mainly to sell DVDs, audio tapes and downloads of conference proceedings. I need to implement a pricing strategy that:

• has different pricing for members/non members

• has quantity discounts within categories that works like this:
  first dvd non members: $25 members: $16
  each additional dvd $18 members :$12

I've looked at: Dual Pricing (might work for member vs non-member... if I can figure out how to identify members); Quantity Discounts (pricing strategy seems to be globally applied); Group Pricing (per item) (can't figure out how to download/install the patch)

I can implement the member/non member pricing when quantity discounts are not involved by an attribute (and verify membership offline). But I'm clueless as to how to implement this crazy pricing strategy.

Help?

Does the discount for members vs non members boil down to the same percentage across the board? If so you could use the Customer Groups to give a discount at the checkout.

No, the discount does not equate to any kind of consistent pricing. Also, the discount is not across-the-board. E.g., the pricing looks like this:

Customer buys 1 dvd: total is $25

Customer buys 2 dvds: total = $25 + 18 = 43

Customer buys 3 dvds: total = 25 + 18 +18 = 61

As far as I can see, a discount module would charge $25 for 1 dvd and $36 for two dvds, not at all what was intended.

After a bunch of scratching and sniffing, I've come up with this solution to my problem:

1. Installed the Group Pricing by Item patch (Firefox wouldn't download the file, but Safari would).

2. Installed Quantity Discounts module.

3. Added code in the Quantity discounts to look up the group pricing category and generate the appropriate discount.

4. Created my own observer hook that upon a successful logon: searches a member database (not part of zencart), examines the membership status and updates the group pricing category for the customer based on whether they are a current member.

It works, but I'm concerned about the amount of custom code, particularly the Group Pricing by Item patch and what issues I'll have when the next release of ZC comes out.

You will have to merge your changes. It's not that big a deal.

acmfox, is there any way you might post all your hard work as a contrib?
I need basicaly the same thing with a few changes that I could make.

If you were clever enough to figure this out, you should have no problem merging changes. :)

But there will be extra work. In particular, although I support Quantity Discounts (and validate it when new releases come out), Group Pricing's author has moved on so the support is somewhat uneven. You would have to debug new interoperability problems yourself.

Good luck,

What version of zen-cart are you using.

This is something I need to have done on my site.

I am running 1.3.7, but trying to install the group pricing by item would not install

I need something like this too. Was it ever added as a mod? acmfox, can you share the info?

thanks,

I am on a similar path.

I'd like to display 2 prices for each item. One is a 'non-member' price the other is a 'member' price. I would like everyone to see both prices to encourage sign-ups. The discount would not be the same across the board as my items price varies greatly from item to item. I'd like them to be able to purchase a membership, and then automatically be added to any list so when they go back and make their purchases they'll get the discounted rate.

Clear as mud? < - that's Southern for 'Make Sense?'

This is exactly what I've been looking for as well...the only thing I would add is possibly the ability to trigger the member prices when the "membership item" is added to the cart...ie, sign up today and get member prices without having to come back later.

I'm tired of making refunds!!!

Thanks!

I'd appreciate the code on this as well. I need something similair.

I would love the code to this too, it sounds like you have the whole concept figured out.
