Drupal Commerce is an incredibly powerful suite of modules for creating e-Commerce sites in Drupal. With Rules based pricing it is possible to create highly complex special offers, vouchers and variable pricing.
However, this can be a minefield of business logic contradiction and complex rule configuration way beyond what your site administrator can manage easily.

This session works through a number of offer scenarios for your e-Commerce site and demonstrates ways to work around some common situations we have encountered.
Some examples:
* Time based price promotions
* Voucher based discounts (percentage and fixed price)
* Bundle pricing
* Limited offers
* Groupon / KGB and any other "group offer" site that will creep up on you - what you should ask the vendor
* Limiting offers per person
* Other offer restrictions
This session assumes previous knowledge of the rules based pricing of Drupal Commerce - or attendence of my Commerce Essentials session if it's on the agenda!
