Paypal 10% discount on Overstock purchases, hmmm, I wonder why:

That's Overstock giving a discount, not PayPal.

Overstock is a liquidator. They buy unwanted merchandise at a big discount and try to unload it. They're always offering "discounts" and "deals".

Is it though? I suppose I'd have to see in what context PayPal is mentioned in the email. In the OP it indeed looks cursory, like they might be mentioned there by accident.
