I don't do EBay, either, but my husband does, and he's found some really good deals on simple items like shirts, jewelry, etc. The "biggest" thing he every purchased was before we got married and he wanted to do something for my daughter. He bought her an autographed Shaquille O'Neal Laker's jersey. Might not mean much to you guys, but it meant the world to Helen!

As for credit cards, I say, don't do them if you haven't done them yet. We don't have any at this point. We have found that using a debit card (straight from our checking account) handles everything we need. As for travel expenses, both of us have corporate issued cards to handle that.
