Product bundling/master-slave products/conversion from OSCommerce

What I'd like to do is have a product in my store that itself draws from other products for it's content. For example, my kit "a" contains items "b" and "c", and when a customer purchases "a" at it's price, inventory is removed from "b" and "c" and item "a" count remains the same, as it's really a "virtual" count.

I know that Zen Cart doesn't have this natively, at least 139h doesn't. I don't know that 1.5 does. I've looked at Better Together, and I don't believe that it's what I'm after, and swguy's Auto Add to Cart is commercial; looking at his demo, it does kinda what I'm after, but it's all out in the open where it may confuse customers.

I have a module from OSCommerce called Master and Slave products that would do exactly what I'm after. I'm trying to convert it using the convert from OSC post, but I've run into a problem. The module requires edits to core files, and the core files are at bit different (Obviously) and if I can't find the code to edit, it's a bit hard to edit, y'know...

So I'm asking for some help, either with a ZC module that actually does what I'm after (that I haven't found...) or some help converting the OSC mod, or even some help to make an ugly hack to do what I'm after, I'm a bit lost trying to follow the ZC code (I know NO PHP, I could fake the stuff I want if I knew where to put it, I think.)

Now, that all the more experience folks are done laughing at me ;-) can anyone advise?

Thanks.

Anyone?

I'm in the same boat. I'm selling combo packages of many items, I want the combos to draw from item's inventory.

This is a question that's been asked ALOT over the years. If there's a commercial module, I haven't heard anyone call it out for attention. If swguy or someone has a commercial module that works like this, I'd love to know.

Me too, I am still in search of one.

@swguy released such a plugin last year: https://www.thatsoftwareguy.com/zencart_bundle_building.html

The bundle addon by the software guy comes close to what others are looking for but just falls short. If it had the ability to allow customers to add or delete quantities, then it would be perfect.
