Today I got this email from Amazon:
Dear Amazon.com Customer,
We've noticed that customers who have purchased The Phantom Tollbooth by Norton Juster also purchased books by Marian Macsai. For this reason, you might like to know that Marian Macsai's Ophthalmic Microsurgical Suturing Techniques will be released soon.
(For those who don't know it, The Phantom Tollbooth is described here.)
