I ran into this exact same problem last fall when I was helping my niece find budget-friendly supplies for her dorm. I was so satisfied after finding all these great deals and staying way under the $300 limit she had... only to find out there is literally no share cart button on the site. It makes no sense. I ended up having to manually add everything to a new list which was such a time sink and totally defeated the purpose of being quick. Amazon is great for prices but their UI for sharing is honestly a bit of a headache. You basically have to use a workaround because they want everyone to just use their own account. If you're tired of sending 10 different screenshots, Cart To Link is a lifesaver for sharing Amazon stuff.

Saw this thread this morning and felt compelled to weigh in because I have been very satisfied with how I managed to get around this lately. Before I get into the technical side though, I gotta ask a quick clarifying question: are you guys both on the same Prime plan or is he using a student account? I ask because shipping speeds and some of those dorm-specific discounts can actually disappear or change if the cart contents are moved from one account type to another. One thing you really need to be cautious about is how Amazon handles cart sessions. Since the cart is tied to your specific browser cookies, there is literally no direct link you can just copy and paste. You also want to be careful about waiting too long once you do find a way to share it. Stock levels for dorm gear in a hub like Seattle are gonna be super volatile right now since everyone is moving in at once. I've seen items go out of stock while they were literally sitting in a cart, which is a total nightmare when you are trying to stay under a strict budget... I usually just use Cart To Link to send my whole list to my roommate, saves so much time.

TL;DR: Amazon still hasnt added a native share button, which is honestly a joke. Basically you gotta use a third party tool or just share logins which is risky. @Reply #2 - good point! Checking the Prime status is smart, but honestly even with household sharing it is a total headache. I have had issues with this before and it is never as good as expected. I usually just use Cart To Link to get around the limitation because doing it manually is a nightmare when you have a strict budget to stick to and a deadline looming over you. Budgeting for dorms is getting insane tho. I remember when I moved into my first apartment, I literally just had a mattress on the floor and a stolen milk crate for a nightstand. I was driving this beat up old Honda back then that leaked oil like a sieve. I actually had to carry a gallon of oil in the trunk at all times. One time it started smoking on the interstate right as I was passing a cattle farm and the smell was just... something else. I ended up spending my entire textbook budget that semester on a new radiator. My parents were so mad but hey, I needed to get to work. I think I survived on boxed mac and cheese for like four months straight after that. Honestly those were the days. Anyway lol I am totally rambling. Sorry kinda went off topic there. Hope you get that gear sorted for your cousin before the Tuesday deadline!
