Have no fear. This is a very busy time for PBA30 and its small staff. PBA30 does not verify donations immediately, and it usually takes them a few days to post the credit card charge. You will receive a letter of confirmation (though it probably will be another week or so). If you have electronic access to your credit card account transactions, you should be able to check to make sure the charge has posted; I imagine you could also call credit card customer service to verify it, too. (My donation took 4 days to post.) If you are extremely anxious, here's a link to the PBA30 customer service form (click on MEMBER SERVICES in the "I want to talk to" block):
