Amazon – way to add all items in an Amazon wish list to your cart

As of now, no. However, the only way other people will see it is if they specifically search for you using your name or email address - If you want it to be private, just change your name to something else, and link only the friends you want to see it using share, and let them know the reasoning behind changing your name so they don't think you're insane. If you want it really, really private, change your email address associated with the account.

Hopefully Amazon will add a feature like you described in the future.

In case anyone is still looking for a solution to this problem, I created a browser extension called "All Prices" that lets you easily see all the price options for each color, style, etc. of an item.

You can find it on the Chrome Store or as Firefox Extension!
