Several years ago, when I could routinely get BBB GCs at 15% off, I was able to use them to buy Visa GCs with some success. However, inventory was very sporadic and success was very store by store, and within stores, cashier to cashier and manager to manager, dependent. When rates on BBB GCs went down, it was just not worth the driving and risk of rejection. In brief, I would not recommend buying any real meaningful amount of these, as your opportunity to liquidate in this manner is very risky. The new Happy Bride GCs will only focus more attention on this technique making it more likely to dry up sooner rather than later.
