Thank you for confirming!  Thanks for ordering.  I ordered one myself and saw on the back of the card that it's reloadable.
Its something cool for us to keep in mind if we ever want to reload our users Subway cards.

Also, I did take a look at e-mailing gift certificates and made some progress on that, but I need to update everyone later as there are higher priority things going on right now.

But I will persistently get back to that project asap as I found one solid and concrete way for BiblePay to e-mail a gift card from the pool with WalMart gift cards.
