The title says it all! The website makes it easy to schedule replacement blades, body wash, etc. And if the next order is coming too soon it's easy to reschedule (delay) the order to match your needs! No pressure to buy anything just a simple presentation of what's available and the rest is easy!
Also, the Harry's blades last a reasonable number of shaves but I also found them much easier to keep clean (rinse) during the shaving process. The brand name blades seem to clog up more easily and are then difficult to clear of shaving matter.
