"But as a consumer, it's wise to realize the long-term implications of your choices. Shop at the big box store for the better price, and lose the small local store that was so convenient; browse the shelves or racks in a brick and mortar store, then buy online? How long do you think you'll be able to do that? My advice remains the same as it was in 2003: Buy where you shop. If you discover a product online, buy it there. But if you discover it in a store, buy it there. Don't save a few dollars now, and lose the opportunity to shop at a local merchant in the future.--Tim O'Reilly, from his column, "Why Using ShopSavvy Might Not Be So Savvy," at O'Reilly Radar.
