Q. Do you have any ideas as to how we can note certain products as made in the USA?
A. The easiest way is to add a new field in "Extra fields" menu. You can call it "Country of manufacturing" or something like that and for US made products, put "Made in USA" in that field on Modify Product screen so it's shown on products details page for those products. After that, if you want, we can do a small customization in the templates to show "Made in USA" banner on those products instead of plain text. Template to modify is /skin/common_files/modules/Extra_Fields/product.tpl
