One product line in, the base price and the largest legal discount out - before a German trade association reads the page.
German e-commerce legal subscriptions (legal texts plus price-display guidance) run about EUR 10 to 50 per month, every month; PAngV section 19 caps the fine for a price-display breach at EUR 25,000.
Buy the full version — $60It takes one product line - pack size, unit, the price you charge, the struck-through price you show, and your own lowest price of the last 30 days - and returns the base price Germany requires, the correct reference unit (100 g or 1 kg), the largest discount percentage you may legally advertise, and which of the 6 rules that line fails right now.
Shopify, WooCommerce, Etsy and Amazon sellers who ship to consumers in Germany or Austria, and the freelancers who maintain those shops. If a listing shows a price per pack, a struck-through price or a percentage off, the German Price Indication Ordinance (PAngV) applies to that listing even when your company sits outside the EU.
Free converters divide price by weight and stop. They print per 1 kg for every pack, so a 200 g jar at EUR 4.99 comes out as EUR 24.95 instead of the EUR 2.50 per 100 g that PAngV section 4 allows, and none of them compare your struck price against your own lowest price of the last 30 days, which is where a discount claim actually breaks.
Free covers the whole calculation: all 6 rules, every pack size, unlimited product lines, no key, no cap, no watermark. The $60 licence adds a different axis - CSV export of a full catalogue check to hand to a developer or a lawyer, and a 30-day alarm that fires before a running promotion outlives its reference price.
German shop-law subscriptions that supply legal texts and price-display guidance run roughly EUR 10 to 50 per month, every month, and a single lawyer review of one campaign costs more than a year of that. This extension is $60 once, runs in the browser tab where you edit the listing, and sends no product data anywhere.
