This could mean as many as ten business days. Most buyers want their new possession as soon as possible, so this method usually does not help expedite the process. Money orders, cashier's checks, and certified checks will carry a fee for the buyer. Their benefit is that once you receive payment it is the same as cash, and then you can immediately send the item to the buyer. However, to offset fees this may cause the bidder to bid less.
Cash is highly risky and inadvisable, allowing for no protection from possible fraud.
Unlike money orders and certified checks cash cannot be canceled or replaced. Credit cards are suggested if you begin a high volume business. They are convenient for both buyers and sellers, expediting the payment and shipping process. Credit card companies do charge the merchant a fee for the service. Escrow services are beneficial for high-priced items.
