If you clicked buy then you are obligated to purchase the item. I m assuming it was a Buy it Now auction. If you don t have PayPal or any other way to pay for it then I would immediately contact the seller and explain the situation. How did you intend to pay for the item? See if the seller will accept your method of payment, if not then you simply can t proceed with the sale. Caution: the seller may make a negative feedback comment.Good luck and be careful next time. eBay is just the auction site, the seller is the one who receives the payment and ships the item.
Ebay does not do the shipping, the seller does, so until they are paid they of course will not ship the item
