When there is a special going on, shops like
APMEX or JM say if you buy less than 20, they'll come in flips. Purchase 20, they'll come in a tube. Often times, I don't want spend $500 or so on 20, so I just order 10. Many times, they come in a tube anyway. I love that because I get a half filled tube to add more rounds to. Yes, I know a tube is less than a dollar but I like getting one regardless. Well, last order I got came in - drum roll please - individual plastic bags. Oh well, you can't win them all. I took them out and stuck them in one of the other half filled tubes.
