That's interesting since Delta e-mailed me and said that Shutterfly was not an eligible partner and that Shutterfly had specifically opted out of this particular promotion.

Were you asking in the context of Shutterfly as a "store" in SkyMiles Shopping OR as a stand-alone partner such as 1-800 Flowers, FTD, etc.?

P.S. I just checked the T&C's again, and Shutterfly is still not listed. While you personally may be able to get an adjustment after the fact since you relied upon their e-mail, I'm not sure the general population can.
