Get Saturn item Installment payment?

I bought a laptop via financing that was accepted and the laptop arrives at Saturn Center on Monday, and I wanted to ask if I had to take any papers like a wage certificate or something? (Financing has already been confirmed online)

If the funding is through and you have a confirmation then everything is fine. You have certainly received all the necessary documents by email. You should certainly print out the pick-up slip and take PA with you.
