You can always put custom orders and sample sizes on inactive during the 3 days or so surrounding your sale. (currently 1/2 of my orders have been custom wedding favors, so I'm ponding if i want to have them out or not during the sale, maybe in groups of 20 or so, not sure). Part is to make the deal so that if falls between price points (either a few dollars short of total + shipping or leaves them a credit; which means they get a less overall discount).
