When sending to tan, the customer needs to pay to go into a higher level bed.

This is done in the Packages screen.

Located at the top of the Packages screen under Package Rules, Click on Show Package Rules.

Now that the Package Rule Screen is open. let's setup the rule.
* Remember the rule you have setup for this package it is found under "Package Rule Set" and "Package Type" on the Package Information page.
1 - Select Package Type
2 - Select Package Rule Name
3 - Select Store
4 - Set upcharge price on bed
5 - Save
6 - Close
That should now show on the send to tan screen for the package with that rule you set.
