I have read with great interest the threads on Debit cards and how to use them for miles. While I am not inclined to join in the fun in this I do use my credit cards to the max. in getting miles from them. Over 150,000 miles per year. My company just opened a bulk mail account at the U.S.P.S and I find that we cannot use credit cards with bulk mail. We can use debit cards. We will be mailing out about $20,000.00 worth of mailing next month and I hate to lose out on these miles. Is there a debit card you can buy using a credit card? It does not have to be one that we need cash back like the Charter one cars. I only want to use it for the post office. Thanks you in advance for the information and I am sorry if I missed it in another thread. Only my second post.
