July Business 75K
Data point for anyone who is interested - I received three business mailers for three different members of my household with an expiration date of 7/31. The last batch I received had an expiration date of 4/30. The April ones were 65K after 4K spend in 4 months. These ones are 75K after 5K in 5 months. I have also received a bunch of the mileup ones but those went straight in garbage so I don't remember the specs. Maybe they are starting to space out the business ones?
