I’ve had 2 successes AND 2 failures loading $200 MetaBank Blackhawk cards at different Walmarts. Both successes were with cashiers who knew how to reload a Discover debit card. Both failures were with cashiers who were unfamiliar — I told them it’s action code 70, and one wanted to review the instructions in the Discover app.

They each said the error was something like “debit not available,” but a transaction/reversal doesn’t appear in the giftcardmall transaction history.

At this point I don’t know if the problem is the Walmart location, the cashiers, or if I’m misleading them by saying “action code 70.” I’ll do some more trial & error unless someone has a suggestion

Edit: Less than an hour after my last “debit not available” failure, I went to a Walmart that had worked before. This cashier also didn’t know what to do, but instead of staring blankly, he got another employee, who instructed him to use action code 70 and the transaction went through (on the same Visa gift card that failed moments earlier at a different Walmart). At this point I’m wondering if some Walmart locations are coded not to accept $200 on MetaBank Blackhawk cards. I’ll update if I find out more
