Just FYI, the current sign up bonuses for these cards are:
Blue Cash Everyday: $50 + 1 yr Amazon Prime
Blue Cash Preferred: $100 + 1 yr Amazon Prime
EveryDay: 10k MR points + 1 yr Amazon Prime
EveryDay Preferred: 15k MR points + 1 yr Amazon Prime
These offers seems to become available not too long ago, though BCE and BCP already had these in the past.
What is noteworthy, the EveryDay and EveryDay Preferred bonuses are Amazon Prime in addition to the normal points, i.e. ED (10k pts+Prime vs 10k pts) and EDP (15k pts+Prime vs 15k pts), compared to BCE ($50+Prime vs $100) or BCP ($100+Prime vs $150).
EDIT: Just noticed this thread
has updated, and EveryDay cards here
. Seems like no need to make this thread...
