"One Day" Shipping

This has really been ticking me off, but anytime I've ordered something that is supposed to have "one day shipping", it ends up getting delayed, lost, or misrouted and ends up getting here two weeks later than anything that would normally be two-day shipping. From a piece of furniture to a small 5-inch box of pills, I've either just had to cancel my orders or wait out the two weeks for something that should have been here much earlier. This hasn't just been a "couple of times", this has been every single time I ordered something that had one-day on it. Has anyone else been having this issue?
