There's still bait-and-switch lawsuits... so advertising has some legal binding. I guess all advertisers know how to write in enough small print to get around it now, huh?

And I guess securities don't have any "this offer good for [x seconds]" on them. That's totally counter-intuitive to laymen, and speaking as a professional layman, I'm pretty sure I'm getting screwed because of it.

Electronic labels - you should be able to reserve a price for a time. Like, you want that shaving cream for $1.45, then you should be able to scan your Walmart member card at the electronic label to reserve that price. Should be valid for an hour, or a day, for up to X number of them.

...because the nightmare of picking it off the shelf, and the price is different when you check-out is just awful for consumers.

...and just to ramble a bit more... Sometimes it's cheaper for me to DRIVE to City A, fly back to my town, and then fly to my real destination than it is to book a flight from my town to my real destination. That's crazy, and I'm totally getting screwed, and I hope laws are enacted to stop that.

Ya, I get the whole "as a professional layman, I'm pretty sure I'm getting screwed because of it" when it comes to HFTs. But if you look at the actual data it's blindingly obvious that the exact opposite is happening. Trading costs have come down enormously!

Iit would be nice if folks looked at the data instead of falling back on their irrational gut logic.
