Collateralized with Starbucks gift cards.
It's probably too late to tell you this now but if Starbucks gift cards can be bought with a reversible payment method such as a credit card or PayPal, then they are likely unsuitable as collateral as they may have been obtained fraudulently.
If that is the case and it is found out by Starbucks they are well within their rights to dishonor the gift cards, leaving you in the red.
your right but luckily that not the case! If you don't know who I am then you should check my trust and check my 3 threads for all the starbucks that I sell. You will find all happy computers that keep coming back and not ONE person has reported any issues with their cards!
