Techniques and systems provide transparency in hidden transaction details for an item. A process comprises crawling one or more electronic marketplaces to identify an item presented in an item offering, extracting offer details in the item offering, emulating an ordering process for acquiring the item to determine transaction details that are revealed after the ordering process is initiated, and presenting at least a portion of the transaction details with item and offer details. In some embodiments, the offer details include a list price for the item, and the transaction details include a true price for the item with a hidden cost included in the true price. The hidden cost may be compared to a threshold to determine if it is excessive. A seller identified with the item offering may be designated with a rating indicative of a reputation of the seller for providing excessive hidden costs with item offerings.
