If you have a CVS nearby, OneVanilla Prepaid debit cards have long been the best option for generating spend with the giftcard-->money order-->bank method of manufactured spending. The became slightly less valuable a while back when Sam Walton's chain of stores stopped recognizing OneVanilla cards as debit cards. This meant that OVs could no longer be used to fund Bluebird cards or to purchase money orders. Well, the door has cracked open again, because Wally World's self-service moneycenter kiosks are now recognizing OVs as debit cards. FWIW, actual Money Center registers still treat OVs as credit cards.
UPDATE: Reports of glitchiness today on Flyertalk. I had the same issues that some Flyertalkers have mentioned: some OVs work, some are rejected as "debit unavailable." No idea why that is.
UPDATED UPDATE: Still Glitchy. Enough so, that I'll be letting this window of opportunity pass by unless I hear reports that things are improving.
