Product Volume Pricing Rules instead of Packages Online

Hi All,

Is anyone using Product Volume Pricing Rules instead of Packages Online?

We really want to move this direction with our CYO's as its functionality is more forgiving on those with different numbers of seats per performance. We can easily do it in the Client since a person is controlling the orders, though we are running into an issue online (we have TNEW) with not being able to limit the orders to a minimum of 5 line items. We want to be able to maintain our subscription guidelines as 5 or more performances per the campaign period.   

I need to know if any of you know a work around through TNEW or in the backend to not allow orders under 5 Line Items to go through online (for the new season only) at the regular price while we are in our subscription period.        

1. 1. What I see now is patrons can place orders for fewer than 5 performance at regular price.
   2. Is it possible to stop the non-qualifying orders during the subscription period?
      1. We do not want less than 5 performances per order, for the new season purchased online during this time.

Any help would be appreciated,

Bobbie Goodnight
