Avengers: Infinity War [SteelBook] [Includes Digital Copy] [4K Ultra HD Blu-ray] [Only @ Best Buy] 
Pre-Order as of now is still at full price, but some may want to reserve now anyways in case it sells out. Free shipping if your cart is above $35 before taxes.
Quick tip to save $1: On the "When do you want your order?" page while checking out, if you click the shipping option, a "$1 OFF order" incentive will appear for the in-store pickup. I noticed this only appears if you click the shipping option. If you default to in-store pickup, you won't get the incentive.
