The weight requirement will not allow you to ship it first class, so the other cheaper option is parcel/standard mail. It would not be unusual to say no thanks, I want the priority with free tracking and faster service.
You will not go in with any 'knowledge'. You will be 'educated' by the postal clerk. :-)
If they suggest something different you say no thanks, priority please. There are many valid reasons that I am sure your shopper brain can figure out for choosing this over the other services.
You will then report on your interaction. If you choose to ship anything other than priority your shop will be rejected.
other than all of the minutiae of the observations and all the other stuff the shop wants you to report on, scenario a goes like this:
1. bring a box (not an envelope) filled with anything that weighs at least 1 lb 4oz to the post office. the box will be addressed to someone at least one zone away. the box will not be a free priority mail box or anything that specifies a mail class.
2. stand in line at the post office.
3. get called to the clerk. tell them you want to mail it (do not specify how). listen to what they offer. choose priority mail.
4. pay for your shipping, get receipt and leave.
