Bank wire and check are the preferred method of payment. Invoices can be sent to use credit cards additional fees may apply.
Overnight shipping after payment is received is my preference. There are always exceptions so shipping will be discussed on a case by case basis.
Accurate descriptions, photographs and conversation before a sale is imparitive to minimize any potential returns. Vintage guitars don't like being shipped back and forth. An authentication period can be granted and will be discussed and evaluated on a case by case basis.
