Depends on the store
All of them have specials all the time. Weekdays are often better, because weekends are super packed and the deals are usually the same. If you have a favorite store, or brand, signup with their emails, follow on social media, or other choices to get all the insider info.
They have better specials during the week (since they get alot of business already on the weekends). Sign up for emails at individual stores, and you get more discounts sent to you as well. Bath & Body Works is one store that is good for that.
