Have VIP sale days for loyal customers
Maybe customers who have been loyal purchasers for a certain number of years and have spent a certain number in 12 months. Example 60% off for a customer who has spent 2000 in 12 months and has been a loyal customer for 5 years.
Don’t just make the sales available for anybody (hence vip sale)
60% off would never ever happen
Sussan do this. After you have spent $500 they give you a $50 voucher for their VIP customers.
