At this time I am only accepting mail payments.
I ship USPS Priority Mail in most cases, books are sent media mail.
There is no reason for returns or exchanges, all items are described exactly as they are with any known issues fully disclosed.
Many items are used or vintage, or new old stock and are therefore sold as is.
Most are tested if feasible, and any operation issues are explained.
It is important for the buyer to know what they are buying and the proper use of the item they are buying.
