Amounts were anywhere between around $300 and $499.95, still declined. Not wanting to get the cards frozen and having to order replacements, I tried day-to-day spending (gas, Whole Foods, Costco, etc.) and never once got another decline on either card. I would tend to agree with theories on here that InComm or Pathward is blocking transactions like these, sensing money order purchases. I just noticed the
"If you need help due to a declined transaction and have sufficient funds to cover the purchase, your Gift Card was most likely declined due to security and safety measures in place to protect your funds." warning at very top of the Vanilla gift card website.
I might try Sutton InComms next, if I can find them around here - maybe Walgreens... But with inconsistent results combined with all of my local Walmarts asking to "see cards 1st," it may very well be the end for me.

USPS is, in almost all cases, blocked from being able to use GCs to buy MOs.. You may want to reference the thread below for more information.

I am uncertain as to whether InComm is twarting your efforts, but I could reasonably say that for the USPS, it's Uncle Sammy who is doing it to you.
