As mother of 3 and a grandmother of 3 I think I know about diapers.  Also I live on social security so I know about living on a tight budget.  Based on that I think that the choices of diapers available at Wal-mart are good plus they give you a choice of quantity.  They are available at a good price so as to not break the bank. the only problem is is that not all stores carry the same products.  I am lucky because the store near me seems to have the best variety out of the stores I can get to.  Also if you happen to buy the wrong size diaper and open the package they will still take them back...
