We buy very little on-line -- we live in a large enough metro area
that *most* things are available "today", in a reasonably short drive.
(Costco is 2 miles, Best Buy is closer to 4, many similar vendors in
that same range, etc.)
Except for clothes and food, we buy most things online.
In just the last few months I bought car parts, a monitor, a desk mount
monitor arm, woodworking finishes, batteries for my UPS, toolboxes, a
tripod, a self setting wall clock, laptop batteries, cell phone, plumbing
parts, undercabinet LED lighting, a grab bar, and a variety of tools.
None of these items were available locally.
We have a variety of home centers, specialty hardware stores, electronic
stores, and department stores nearby. Unfortunately, most local stores
only carry the most generic consumer level items, typically the low end,
low priced items that appeal to the masses. Even the specialty stores
typically have a limited selection.
I can find very specific items online, do my shopping at 5am in my pajamas,
and have it show up at my door in 3-4 days. What's not to love.
