is something like TOR worth using?? Like I don't need to go private often but is incognito private enough? It's fine for buying stuff in secret i think
I don't think you should need tor to tell the truth. If it's some "in secret" one would assume it's illegal or you don't want people to know you ordering X item. So... I would stay away from it.
Also the problem is eventually X item needs to make it to you. So at sometime there is something attached to you to get the item. So yes BTC if never used can be anonymous but once used for something I think it loses a lot of that part of being anonymous.
