I'm clearing out my storage right now, and I'm offering a whole bunch of S1 CTEs with barely any owners if you want to use them for bank transfer cards. They can be found here:

If you wish to purchase one, post in this thread with the card that you want to purchase, and the price will vary from 1-3 bank depending on owners.
