I've been hesitant to post this deal because Delta Airlines is notorious for blocking members from redeeming miles (one of the worst in the industry), but perhaps you can salvage some value out of it.
Here's the deal: New Shutterfly members earn 1,000 Delta SkyMiles after making their first purchase. Simply buy one photo, add shipping, and the total cost comes to $1.84. Here's the link.
If you are within 1,000 miles of reaching your next "milestone" with Delta, then perhaps this is a deal worth pursuing.
(Edit: Received a note from a reader reminding us that this type of transaction automatically resets the expiration date of Delta SkyMiles another 24 months. Definitely another benefit. Thanks!)
