If you want to quit stock I suggest you use simple clearly priced signs for your dump bins. Half price or 75% off may sound good to you but to some customers they don’t know what they mean. $1 is easy to understand. Everything on the display or in the bin is $1. I don’t have to think about it.
I have seen 75% off sales where everything is close to a dollar not work – until the 75% off sign is replaced with $1.
Simple signs in retail are vital to driving shopper engagement – especially in locations where you have plenty of foot traffic.
