ok guys so i just finally set up a po box. i usually have packs sent to my physical address but for certain reasons i needed a po box. I guess im just looking for opinions on what my first test pack should be. should i test with a gram of oil? or try a grinder or something like that? my po box is one of the small ones so i guess it makes me nervous.
The conventional wisdom is that you should "season" a new PO Box. Subscribe to junk mail or what not to get flow through it. How much good this does is up for debate IMO. I don't think its at all suspicious to open a PO Box and get mail to it (novel concept, yes). I tend to believe that most mail is intercepted before the "last mile." Does the post office where you got your PO Box have those lockers? If so, then they'll just stick packs that are too big in there and drop a key in your POBox for you to use. That way you don't need to interact with staff. One thing I seem to remember hearing but don't know the validity of it is that if you get packs that don't fit too often, they won't use the lockers - they want you to buy the larger PO box and not buy the cheapest and actually need something bigger. Just something to think about.
Otherwise, you'll be interacting with PO staff should a pack be too large. Probably the biggest snafu on PO Boxes is not using the right address. Always verify the full address of your new PO Box, including zip code. Sometimes the zip isn't what you think it will be.
