Good tea and coffee there is really expensive. My wife would always bring in tons of her favorite teas. Boxes of it and we never had problems. Next time, you should call them out and ask what exactly isn't allowed and why.
Yes, it was just myself when I first moved there. 7 suitcases for myself but I was making a permanent move from the USA to Buenos Aires. They did go through everything but this was a while ago. I had a lot of electronic items as well but I just said it was for personal use which was true. That Herman Miller Aeron chair here is probably 3X the cost as back home. When I came originally I had a student visa and that's probably why they cut me lots of slack. There wasn't much tourism back then.
How are you adjusting to life in Buenos Aires
@Oatmeal? I think you mentioned you live out in the Northern suburbs. Hope you had a great move and enjoying life in BA.
