I was just at Lowe's last evening, looking for an O-ring to fix my Innovations Second Wind IH. I had looked at Home Depot before, and terribly disappointed in how things are layed out in that store. At Lowe's, it literally took me from the time I walked in the door, to go to the plumbing aisle, to finding the O-ring/gasket section, to using the selector sheet to pulling a packet off the shelf - all told, probably three minutes. At Home Depot, I never did find an O-ring that satisfied my mind.
