We are currently using Smart Pricing with a minimum nightly price of $230. I'm looking fill a 10 day window this month and want to run a custom 20% promotion. When adding the promotion it shows a nightly price of $179 (before promotion) and after the 20% off it brings it down to $143. Any idea where the $179 is coming from. We are looking to offer 20% off our lowest minimum nightly price of $230. Thanks!
