FTD is augmenting their standard United miles offer with 2000 additional bonus miles if you make two purchases by October 31. At least that’s the offer I got by email yesterday — 25 miles per dollar plus 2000 if you make two purchases by October 31.
So then I looked back in my archives and found a relatively recent 30 miles per dollar offer. And lo and behold it came up as 30 miles per dollar plus 2000 bonus miles for those two purchases by October 31.
Take two $50 orders — that would yield 5000 miles, or 50 miles per dollar, exclusive of tax and delivery charges.
