NewEgg has Malwarebytes 3 PCs / 1 Year (Key Card) [newegg.com]
for $39.99 less $10 with code WINSALE24 for $29.99 with free Super Eggsaver (4-7 bus. days) shipping.
The coupon does NOT work for the NewEgg digital download version but I'm willing to wait a few days to save $10.
MalwareBytes website sells code for $49.99.
