post/heureka/v1/product/offers2 credits

Every shop offer Heureka lists for one product — the price comparison itself. One row per merchant: shop name, Heureka shop score and how many ratings it rests on, the price (numeric and formatted), the stock line, the delivery line and whether delivery is free, the merchant's own listing title, and a working click-through. Rows are de-duplicated (Heureka repeats promoted offers above the list) and ordered cheapest first, with the product's own price band alongside.
