Amazon offers the
Playtex Diaper Genie 270-Count Refill 3-Pack (810 refills total) for $13.59. Check out via Subscribe & Save to drop it to
$12.91. With
free shipping, that's $4 under what you'd pay in-store locally and the lowest price we could find, although we saw it for a buck less in April.
Note: Be sure to cancel Subscribe & Save after your order ships to avoid being billed for subsequent shipments.
