I hadn't seen a mention of this yet. I signed up for eMiles yesterday and have earned 340 miles between the sign up bonus and other offers. But I noticed on the left side of the page there are a few sponsers that award eMiles for purchases such as iTunes and Nordstroms. It's nice to know that if I fail to get the remaining 160 miles in a reasonable timeframe I can buy a few gift cards from iTunes to make up the difference and score the hit. At the rate of offers at the moment, I don't think that'll be necessary.
