[ic] Single Unit and Case Quantities in IC 4.9.2

[interchange-users@icdevgroup.org (Alex)]

First, thank you for such a great product. We have been 
implementing without a hitch and have found most answers 
through the mail-list archives and documentation.

That said there is one task we have had difficulties 
locating a solution to in IC4.9.2:
We have a line of products with custom attributes which we 
would like to offer drill down searches on. This includes 
attributes like brand and size (i.e. search for all Sony 
products or search for all large shirts). What is the best 
way to add support for these custom fields and then 
generate the respective search links?


Additionally some of these products offer both single unit 
and box quantities (different sku's) and we would like to 
group the two together. Ideally the same product display 
page would present an option to buy the single unit(buy 1 
item - $x) and if available the case quantity as well (buy 
1 box of 80 - $xx). We would want to eventually take this 
one step further where a retail customer would see single 
unit and box quantities while a wholesale customer would 
see box quantities and true case quantities (x boxes per 
case). 


For example: When viewing a lollipop as a retail customer 
you could purchase a single lollipop or buy a box of 
lollipops (if stocked - if not, box option would not 
appear). As a wholesale customer you could purchase 
possibly a single lollipop, a box of 80 lollipops, or a 
case of 6 boxes. All would have different sku's.


Has anyone on the list implemented something similar or 
know where we can look for existing support? Any pointers 
in the right direction would be greatly appreciated and 
I'm sure any work we do we would be happy to give back to 
the project.
