Building on the earlier suggestion about those extensions, I would suggest being pretty careful before installing more plugins. I remember trying a similar cart sync tool a while back and it basically ruined my browsing speed. Tbh it felt like it was constantly pinging servers in the background, making my whole system lag and get all glitchy whenever I tried to check out. Instead of third-party stuff that might be a privacy risk, I honestly think you are better off just using the List feature built right into Amazon. You just make a list, invite your husband as a collaborator, and he can move everything to his cart with one click. Its way safer and keeps your browser running smooth without all that extra code cluttering things up. Quick tip:

• Create a dedicated Shared Cart list
• Use the Invite button so he can add or remove items too If youre really worried about performance on older hardware, maybe look at something like the Samsung Galaxy Tab S9 FE 128GB for your shopping... it handles the mobile app lists way better than a cluttered desktop browser with ten extensions running.

Helpful thread 👍

Been using this for years, no complaints

Can vouch for this

Honestly, you gotta look at the performance side of things if you're gonna be sharing big lists. I’ve been testing how different sync tools handle heavy DOM manipulation on the Amazon checkout pages, and it's crazy how much they can vary. Basically, if you don't want your browser crawling to a halt, you should just stick with any of the major open-source dev teams from the Chrome Web Store. They tend to have way cleaner code and don't bloat your memory usage while you're trying to shop. I did some benchmarks recently and the difference in page load times is huge when you have 20+ items in the cart and a background script is trying to scrape the data. Just grab a utility from a reputable developer that focuses on browser optimization and you'll be fine. Performance-wise, it's night and day compared to some of those janky, unoptimized scripts you find on random forums!!! If you want it to actually be reliable for you and your husband, optimization is key.
