While you will probably create multiple funnels with multiple offers, you'll want your first funnel to act as your "base funnel." This funnel will always live at the very bottom of your funnel priority list. The funnel should capture any orders that didn't fit the funnel criteria of funnels higher on your funnel list.
Think of a pyramid when deciding funnel priority. You want your most specific funnels on top and the most general funnels on the bottom. This will maximize the effectiveness of each funnel.
Priority also lets you choose which funnel to display if multiple funnels share the same criteria. For example, if your customer buys a particular product, you can choose which funnel has priority if Funnel A and Funnel B are both set to display. Click on any funnel, scroll to the bottom to the Priority section, then click "Change."
You can always change the priority of your funnels if you have more than one.
Then, simply drag and drop the priority order.
You can also do this from the high-level funnels page by clicking on "Manage Priority".
Note: If the offers in a priority funnel are skipped (due to lack of inventory or if "hide offer if product in initial order" is selected), the next priority funnel will be displayed, if exists based on criteria.
Now, it's time to create an Offer for your "base funnel!"
