Best Buy offers the Home Alone: 25th Anniversary Steelbook Edition on Blu-Ray Disc / DVD / Digital HD for $10.99 with free shipping. That's $4 off list and the lowest total price we could find.

Of note, Amazon offers it for a buck less without the Steelbook packaging with free shipping for Prime members. (Non-members can spend $49 to bag free shipping; otherwise, it adds $4.98.)
