Showing amazon product prices...confused

I think that you are taking a risk without the time stamp. If you update the prices every minute and you have a lot of products, I am not sure how many server resources are needed and if this might slow your site.

You are not allowed to include Amazon prices on your site, unless it is done by one of their feeds. They change prices frequently. A customer seeing one price on your site and a different one on Amazon might be confused, and confusion will stop a sale.

I am using wpzonbuilder. Is it ok to display prices with timestamp?

Yeah, it WOULD be nice, efficient, etc... if you could cache the feeds. But there is TO much that can happen. If you display info straight from their site, when they send it, there isn't much they can complain about. Cache it, and technically YOU would be breaking the law, but THEY have to make good on it, as far as customers, and maybe the law, are concerned.

And YEAH, it IS illegal. They passed laws DECADES ago stating that they best effort should be made to keep things stocked reasonably, and sell at the advertised price. If the quantity is low or erratic, it should be indicated. If it is a one off item, like a car, there may even be a law(as with cars) to identify THAT specific car! Failing to do things may force you to offer an item at LEAST as good at the lower price.

This all stems from a time when people would offer lower prices and claim they ran out, or the special deal was done, and often try to UP SELL. That is known as BAIT and SWITCH! Bait-and-switch - Wikipedia, the free encyclopedia Anyway, amazon CERTAINLY doesn't want to be known for doing that, so they expect YOU to follow those laws if you deny them the opportunity to have such control.
