How do you explain the value of money to a 5 year old? For the last week or so, Maddox bombards (putting it mildly) Teague incessantly with this master plan of the 2 of them heading to the store this Saturday & buying a new xBox360. Keeping in mind that the units are $300 and we've already had 2 that have broken (nice craftsmanship, Microsoft!), we just can't seem to get the point across that this purchase is unnecessary.

T(eague): But xBox's cost a lot of money, Maddox.
M(addox): but you can go up to a boy or girl at the store and ask them for a lot of money and I will carry the xBox to the car

Help!!!
