You are right to be skeptical about those browser extensions. Giving any third-party software access to your active Amazon session is a major security vulnerability that I would suggest avoiding at all costs. I have seen far too many people lose access to their accounts because they wanted a shortcut. For a $300 budget of kitchen essentials, the safest route is usually the built-in Wish List feature, though it can be a bit clunky to set up for 15 different items. If you are looking for something faster but still want to maintain a high level of security, you might want to consider using Cart to link instead. It is a much more reliable way to share what you have found without compromising your login credentials or personal data. Regarding the actual items, if you are buying kitchen gadgets, just stick with any products from OXO. You really cannot go wrong with their quality for a housewarming gift. They are basically the gold standard for durability and ease of use. Just make sure to double-check the shipping dates before you finalize anything. Being cautious with your data is definitely the right move here... too many people are careless with their account security these days.

Building on the earlier suggestion, unfortunately Amazons session management doesnt allow for shared cart IDs. Its a mess. I had issues with their native sharing failing on larger kitchen gadget lists before too. Honestly just search YouTube for amazon cart sharing guide. Theres a specific video that shows a secure mobile workaround. Just search it up.
