I think once a week is perfect.
Keep in mind, the longer you allow people to get things, the less complaining you will receive. A week is a perfect amount of time. We're all (most) adults now - we hold jobs and some of us are juggling school. It would be nice if things weren't on sale for a very short period.
Maybe put them on sale during special occasions and let them be on sale for a week? During the Christmas/Halloween time, put ears on sale once a week for that month. (Orange ears, black ears, Green ears, gold ears during Halloween time and Red ears, silver ears, blue ears, and idk, dream ears during Christmas time) Just once set per week.
