Setting up different pack configurations on single item entries

[DeacoN_Carr]

Hi all - I have a situation that I would like advice on:

Lets say I'm selling beads.  I want a single catalog entry for these beads.  I have 1 big bucket of them, that I want to sort into different size bags as they are ordered.

I want each bag size to have their own price, and show available quantities based on the remaining beads left in the bucket (divided by the pack quantity)

 

Example:

Bucket = 100 beads

Single Item entry - customer can select their bag size:

25 beads = $6.00 (4 available)

50 beads = $10.00 (2 available)

75 beads = $13.00 (1 available)

100 beads = $15.00 (1 available)

 

Does anything like this exist?

Thanks!
