What are the rules for price reductions?

• The listing is online.
• No other promotion is currently running.
• The current price has stood unchanged for at least 5 days.

The reference price is automatically the lowest price the listing had in the 30 days before the promotion started. You can't enter it yourself. The promotional price has to be at least 10% below that reference price.

A promotion runs for at most 14 days. After that, the promotional price automatically becomes the regular price. You can end it early at any time; the listing then returns to its previous price. While it's running, the price and tax settings are locked.

A reduction of 60% or more asks you to confirm it first.

• Only through the Aktionspreis function: outside it, statements of a reduction, comparison or saving aren't allowed in the listing text, the title or images. That applies above all to struck-through prices, percentages, and comparisons with an RRP, a list price or another seller's price.
• The reference price has to be genuine: raising the price shortly before a promotion just to inflate it counts as misleading.

You stay responsible as a shop for the lawfulness of your price claims, even when using the Aktionspreis function.
