Buying syringes and needles online

Hi all! So, I've had to stop E for a month and a half due to personal issues, but I am resuming this month with a DIY approach (for financial reasons), and one thing I'm worried about is buying syringes and needles.

I know ShopMedVet is often recommended, but from what I see, they don't offer discrete shipping. I don't want my parents to see a package of syringes and needles sitting in the mailbox, lest they get suspicious and ask me about them. Are there any sites that offer discrete packaging?
