If this was for a purchase on ebay, the seller must except all paypal funding options.
A seller can't tell you to only send a e-check. Why does the seller want an e-check..
Some bank funded payments are not charged a fee to the seller, it depends on how it is sent.
Did the seller tell you how to mark the payment when it is sent., like "goods", servicee", or gift.
An instant bank transfer is actually an e-check, its just instant because of your back up funding source.
