O-tay....
There are 2 possible PO's I would go to. The "nice" one in town, and a little dinky one out in the sticks on the way home.
The one in town is, well, nice. Better hours, more people, and vending machines because I have odd hours and can't make time to go there and actually buy stamps from someone. And it is NOT posted, whereas the "little dinky one" IS posted. But since "little dinky PO" has really lousy hours since it's staffed by one person, I hardly ever go there.
Bottom line is, I may buy stamps once every 2 months, and I tend to just get them alone. So I'm disarmed for maybe 2 minutes max.
Bi-Lo does not HAVE to post, so sod 'em. The post office I visit is not posted, but until I do more research, better safe than sorry....!
