yep, u can only present it straight forward and honestly to the customer.

u advertised a healthy animal and that is the expectation from the customer. beyond that, u could tell the customer that u will take the BP to a vet and will nurse it back to health before she can pick it up. u cannot in good conscious transfer ownership of a sick animal to her.

in any of these cases, the customer may back out. it's unfortunate. u cannot do anything but good care for your BP and provide good customer service. if u plan on breeding and selling a lot of snakes, this will help u keep your good name - even if u lose this 1 sale.

good luck, keep us updated.
