I'm not 100% sure it did or didn't work but I had used it back to back (added another before the other expired) credit parties and I don't think it went thru. The first one worked but I don't think the others did even thou it took my credits. How long does a credit party last for and the frequency? It's 10,000 credits to start and I wonder if it gives out that much to everyone? Just wondering if it's worth doing and if there's anyway to check to see that mine went thru and if there's any issues with it.
