That'd be an even better analogy if both stores were furniture stores, or hardware stores.
You can pick up wood at Home Depot and build furniture
IKEA is like those special LEGOs that are for recreating the White House or the Taj Mahal.
I've never been to an IKEA store, but I do frequent Home Depot....in fact just bought a fridge there about a month ago.
True. And my wife loves both of them. :)
