Paypal really does make the process easy and safe, but its not for everyone. The only problem that I have with Paypal is that they force you to adopt their return policy. Depending on the products you sell and the methods you ship, this can be a problem.
If a customer ships an item back to you, opens a paypal case and provides a tracking # showing delivery of the item, Paypal will always refund the full price paid and the original shipping cost regardless of the circumstances and your return policies.
If you have a liberal return policy, and you dont ship overnight or 2 day its probably OK.
As a customer, there is no doubt it the best way to pay. Especially if you use your credit card to fund the payment. As a seller, it creates a potential liability that is unacceptable for some business models.
I hope that we will have the option of offering Paypal and or another payment option.
