Through 11/21, Office Depot has two things they never do: a $10 off $40 coupon (use code 77767594) and free next-business-day delivery on any order (it is usually on orders over $50). What should you get? Cases of bottled water are $7.19. Add 6 to your cart to get to $43.14. Enter the $10 off code and pay just $33.14 plus you don't have to lug them home from the store! For those of you crunching the numbers, that comes out to just $5.52 a case and $.23 per half-liter bottle. You could also buy 11 cases for $79.09 and use $20 off code 22799621, that is just $5.37 per case. Delivery is free to your home or office the next business day. The brand is based on your region - I received Ice Mountain.
