Other deals worth hitting: Along with WW and GotG2, Logan on Blu-Ray/DVD/Digital is $8.99 (78% off)! Spider-Man: Homecoming is $7 for the same combo pack, which is supposedly just 22% off, but I'm guessing that's a price mistake (so grab it). John Wick: Chapter 2 is $9 (70% off), as well. For slightly older hero movies, Deadpool is just $6 for the combo pack; ditto Batman v Superman, although that's just for the Blu-ray.
If you want something for the younger folks, Sing on a Blu-Ray/DVD/Digital combo pack is $6 (74% off).
In books, although it's too cheap to qualify for the $5 coupon, Andy Weir's Artemis is $12.15 (55% off). Meanwhile, the new hardcover Fantastic Beasts and Where to Find Them is $15.74 (55% off).
And finally, because I know it's the office product a lot of people love, the Brother P-Touch PT-D210 Label Maker is $9.99 (75% off).
