Syringes I have ordered aren't labeled syringes on outside It's similar to ordering sex toys, comes in a discreet package. Ar-r has them but I order most mine off amazon anymore. Luer lock is my preferred.

I use an empty milk container for my used sharps and I keep them in the top of my vanity closet in bathroom along with anything else. When milk jug is about half full or I happen to have another one empty I dispose of it in the trash. If my neighbors want to dig through my trash, they have bigger problems.

clarky's answers pretty much summed up all mine.
