I'm probably the only one who comes to Vegas and has to stop at a 99 cent store, but if you plan on staying for a few days, you HAVE to make a pit stop here.
The selection is outrageous, but I really do only come here to stock up on soda and snacks. Water gets boring at the hotel and you really don't want to take anything from the minibar. We always make a stop here the first day we get here and grab enough munchies, juice and soda to last us our entire stay.
You can probably do the same, but you really can't beat the deal!
