Twenty years on, and I can still link to any item at Amazon as long as I have it's ASIN, and using the template:

    https://www.amazon.com/exec/obidos/ASIN/<asin id>

Say what you will about Amazon (and Jeff Bezos), but I don't think they've broken a URL to any product of theirs ever.

View on HN

Not broken perhaps, but I regularly click a link to a product and get a page about a totally different product.

My understanding is that product pages aren’t immutable, so sellers sometimes change their content instead of making a new page to keep the SEO the original page accumulated.

Having public edit history + permalinks to specific immutable revisions of product pages would be nice, but I could see how they’re not incentivized to add it because they don’t want ppl demanding an older price / feature that got edited out later on.
