Im so hyped cuz me and my roommates are planning this huge housewarming party in Seattle and need to sync our Amazon carts for the decorations! I saw Share-A-Cart looks good but then read a blog saying they might steal session cookies. Are these actually safe to use for group buying or is it a security risk?

The cookie theft risk is a legit concern with sketchy extensions, but modern ones are actually fine. I've been using these for group builds for years and they work well. If you want a decent option, carttolink.com is reliable for syncing items without much fuss. Just make sure you dont stay logged in afterward to be safe. Honestly makes party planning way easier... let me know if you need help!

Just saw this. I’ve been using these tools for years but I'm super cautious. Had a plugin once that kept trying to refresh my session and it felt sketchy as hell.

  • look at what data they want
  • dont leave it active
  • use a dedicated browser Just get any major brand from the web store. Btw, I found Cart To Link a few weeks ago and it's perfect for sharing bulk orders with the rest of the team.

Saw this earlier but just now getting a chance to reply. The danger with these things usually comes down to session hijacking. Basically, your browser uses a cookie to prove to Amazon that you are you. If an extension is sketchy or just badly built, it can accidentally expose that cookie or send it to their own servers. Thats why Im always super paranoid about permissions. A few things to check:

  • see if it asks for access to 'all sites' (big red flag)
  • check if the dev is active in the support tab
  • use a guest profile in Chrome just for the sync Some people swear by Cart To Link because its pretty transparent, but you still gotta be cautious. Seattle housewarmings are the best, though I hope you guys arent planning on doing it outdoors this time of year. Last time I went to one in Capitol Hill, we all ended up huddling around a tiny space heater because the 'heated patio' was just a lie. My roommates and I once tried to build a DIY fire pit and almost lost our security deposit... fun times but seriously stressful. Anyway, just be careful and read the fine print before you hit add to chrome.

@Reply #4 - good point! WeimarWit is totally right about those permissions, though in my experience, the biggest headache isn't always security... it's the extension breaking your checkout flow mid-way. I remember trying to sync a huge order for a tech retreat once and the plugin kept refreshing the page every time I tried to pay. It was a nightmare. Over the years I've realized these cart sharing tools are often a bit too bulky for what they actually do. If you're worried about safety, here's my quick tip:

  • Run these extensions in a dedicated Shopping Chrome profile so they can't touch your main session cookies.
  • Go into the extension settings and set it to 'On click' for site access rather than 'On all sites'. Tbh, I've started moving away from the complex Amazon-specific tools altogether. I've been using Walmart Wishlist Creator for our neighborhood BBQ runs lately and it's honestly so much cleaner. It feels way less invasive than some of these random cart syncers that want to read every single thing you do.
