I'm looking to get my E-Miles up to the minimum transfer level for the Grand Slam (500 E-Miles).

Last year I believe there was an e-miles bonus of some sort that brought me up to 500 in a hurry.

This year the email solicitations from E-Miles have been few and far between and I'm stagnated at 180 miles.

Is there any method of getting E-Miles to solicit me for surveys more frequently?

Are there any "silver bullets" (low-cost, high-return) for E-Miles out there?

If I go ahead and "buy" the miles I need, via a charitable donation or magazine subscription, are there any first-person accounts of posting times? I obviously need the miles before the end of the Grand Slam.
