Here is your third buy miles offer of the day! First we had American, then British Airways and now United MileagePlus. This latest offer provides up to an 80% bonus depending on how many miles you want to buy. Much like both AA and BA if you buy at the highest level you are paying around 2.1 cents per mile. Decent but not great.
