This is of course fraud.
You think some guy is getting starbucks giftcards for a 100% and selling them for 20-50% for karma?
https://www.reddit.com/r/starbucks/comments/2c973a/gift_card_cash_outs_is_getting_ridiculous/This is why he said transportation matters.
Here is his guide
1. Get giftcards any way possible
2. Go to starbucks try to cash out.
3. Starbucks cashier is either dumb and says buy something and I will cash out your $50-$100-$500 card
4. Oops she said no they can only do $10 or lower.
5. Buy X 10 dollar cards with your gift cards.
6. Drive to every corner and profit till you go to prison.
Also as he said it depends on your state, so this guy is going to sell you his garbage guide where most states don't even have a GC cashout law.
