If the rare unfortunate event of shipping damage happens to your purchase, a return is not required, but a photograph of the damage must be provided before any refund or replacement can be issued.

No. They are estimates. The vast majority of orders will arrive within the dates shown, but sometimes delivery companies experience delays. I only use professional delivery companies and am generous with delivery estimates (if they say it takes up to 10 days, I will use 15 for the upper estimate), but sometimes even these can be exceeded on rare occasions. If you absolutely need an item by a certain date, please consider an express upgrade or contact before purchase, as another option or courier may be available, although these can often cost more.
