If their terms _guarantee_ 2-day shipping to contiguous US, does that mean there's some recourse to a customer when that is not met? Cause it is routinely not these days for many people I know.

Every time Amazon misses a guaranteed delivery date, I send a quick note to customer care and get a free month of Prime added to my account. Takes under a minute and I've never had to even respond a second time to one of these threads.

There are times when 2 days is not the guarantee, which is slightly annoying, but for most items, 2 days is.

So it's unrealistic to expect a multinational corporation to be competent enough to ship XBox controllers and eight-inch pipe fittings to their customers, if they're on an island? Because that's what the parent comment is talking about.
