It is not quite finished, but here is the display of your work at the Old Town farm. The Rancho one will be less elaborate, but with instructions for customers who want to see more to go to Old Town.
The boxes are on the shelf above the Postmaster’s desk. On the left are a half dozen lift-top ones, and some screw-top ones on the right. Behind each group is a summary chart from the website, showing a picture with the item numbers and prices. Another copy of the chart is on the desk, and a third copy is with the cashier. One of the screw-tops is on the desk for people to fiddle with. I am a bit worried about shoplifting, so there is a security camera between the two groups of boxes on the shelf. I will put a smiley face or something on it so everyone will see they are being watched.
