Here's my challenge. We are a printer that produces custom calendars, and we offer quantity discounts like this sample:

1-4 $35 ea
5-9 $25 ea
10-19 $20 ea
20-49 $12.50 ea
50-99 $7.50 ea
100+ $5.00 ea

When a client places their order, they will also select custom text fields, 2 custom colors, etc. This is working properly.

However, what I can't figure out is when a client will come to the site and add their order of customized Calendar 1 of say, 25 items. Then, they will get a colleague to place an order of 25 for the same Calendar 1 with their own customizations. However, they will then get the discount for 50 items, as opposed to the correct discounts on 25 items each. This is a problem.

We are poised to let each client only order one product type at a time, though we're not even sure how to do that. I'm not sure of the best way to approach limiting this in the configuration.

Thanks,
