When ordering an item from www.sears.com and paying by PayPal, the PayPal site presented me a click-through that read "Use PayPal for future payments to Sears Holding Corporation.". The click-through is deceptive in several ways:
I have never seen another merchant hijack a PayPal account this way for one-time purchases picked up from the store. It is clearly not common practice and is not expected by the consumer. SHC is intentionally using visual deception to dissuade the consumer from cancelling out of the transaction so that SHC can gain increased control over the consumer's PayPal account. Sears has lost all my future business.
To make matters worse, PayPal makes it difficult for the consumer to find the interface for inactivating preapproved payments, and PayPal requires that one payment method always be associated with preapproved payments. So if a vendor sneaks in like this, they are guaranteed some form of payment. The consumer can never say to PayPal "Don't ever use my credit card for preapproved payments". I'm disheartened that PayPal has stacked the deck against the consumer this way.
