True, CC are also good because they build your credit(if paid on time).
I also like the CC because at the end of each month, we receive the itemized statement of all our spendings and we see exactly where every penny went.
At the end of the year, we take out all our CC statements and review them. Then we can see where to cut expenses for the next year.
Again, CC only works if both husband and wife are very strict with it.
