If you are an online shop operator and you depend on paypal your business is at risk and you are losing money. Most shop operators wrongly think that no having paypal as checkout option will lose them money but in fact it is the opposite. At CaseBuddy more than 85% of abandoned orders were orders that were checked out through the paypal system.
If you want to reduce abandoned orders and increase the profitability of your business the first step would be removing the paypal checkout option.
