LUCID 10 Inch Gel Infused Memory Foam Mattress Queen Medium Plush & AmazonBasics Hypoallergenic Vinyl-Free Waterproof Mattress Protector bundle $130.15 @ Amazon

From Amazon, you can purchase this bundle for discounted price of $130.15 right now. Bought separately, these two items would cost $285.64 in total. When bought in a bundle, it gets discounted to $130.15. The bundle savings is thus $155.49. I am guessing this is a price mistake.
