Does PayPal permit transactions for pre-sale items?
Pre-sale items are advertised for sale before the seller has the items. Often, these items are sold before they are available to the general public. Or, the seller uses the funds from the sale to purchase the item that has already been sold.
PayPal permits pre-sales on a limited basis, only if the seller guarantees delivery within 20 days from the date of purchase and clearly identifies the item as a pre-sale. PayPal may apply additional conditions, such as proof of the seller's ability to successfully deliver the product: supplier information, purchase invoices, postage information or proof of delivery.
