I guess I am the latest in the long line of unfortunates that must deal with these problematic "credit errors". I have tried to redeem a credit as of about 15 minutes ago.(It was only a $5. credit though,not a ten)and it has given me the frustrating statement of "invalid code". I would like to be helped as quickly as possible,so that I may enjoy this credit that came with my recently purchased BD.Thank you in advance for any replies,whether helpful, or not.
