How do you know when you have Amazon Prime?

I don’t want it or I hope I don’t have it. I do keep my card saved on Amazon though it makes it easier for me when ever I want to buy something. But I haven’t purchased or clicked nothing regarding Amazon Prime. But when they give you that tape that says Amazon Prime does it mean I have it cause of the tape? Lol

I never thought nothing of it my sister came to visit me and saw me opening my package and said “you have Amazon Prime?” I said no. I think she said that because she read that the box was taped in Amazon Prime.

Or does everyone’s package come exactly like mine? Plse tell me they do I don’t want to find out I have Prime 😩
