- Small stores making their own shelf labels
- Worth noticing
- Multipacks and “2/$5” deals factor into unit prices; labels under one inch show UPC digits instead of a barcode.
Field notes
Items can be entered one at a time or pasted as CSV/Excel-style lines, then assigned to a selected label or paper format. The tool derives unit prices across weight, volume, and count units, and handles multipacks and “2/$5” deals. UPCs become barcodes only on labels at least one inch tall; smaller labels show the digits. Printer alignment can be adjusted in inches, with a test-page workflow for checking drift.
