Do these get flagged in a obvious way when they go bad or just show up as a empty card?
what do you mean?
I guess I am presuming something about the card and it was a bit of a leading question.
Was wondering if the card would show up as stolen at the transaction time if it was seen as bad or if the barista would just tell me it was a empty card,meaning no funds in it.
See a lot of people selling and I would not mind going to starbucks if it was this cheap on a daily. But I do not want to run into issues with the store and have the line up looking at me like I am a scumbag,which I just may be.

I understand your concerns . but your peace of mind , my stb sold not die , and you can use it without problems as the card is die . so I was sold for $ 35 for balance is $ 100 . if you do not believe you can buy in advance a little and test
there are many reputable on the board they have bought and have positive feedback , you can check out my blog
