Is it suspicious

Do you think my post man will get suspicious if i keep getting orders from the same science store?

Generally, I don’t think any regular working person actually cares that much what you do with your money or your body as long as you’re not endangering or financially depriving them or their loved ones. Keep your house maintained and in order, be kind and let them know you appreciate them. Don’t perpetuate the stereotype.

Agree with necromedic. I worked for that devil company for a couple of years and never once gave enough of a shit to pay attention to the places people got their packages from. Plus there are so many in one day, even if the post man hates you for some reason it would take a lot of effort and willpower to remember something like that for one specific address. They all blend together. There also isn't much they can even do about it anyways. At least from my own experience.
