PSA's value grading, without the bulk discount, is $24.99 per card so if you're doing three cards you'd pay $24.99 each, plus shipping to PSA. With me you'd pay shipping twice, but only $16.99 per card. So you'd save $24 on the grading, but have to pay a second shipping charge. For three cards, it would definitely not cost $24. Three cards would fit in a small flat-rate ($10) or, like I said, I could save you another $4-5 if you wanted me to ship back to you in a standard bubble mailer.
