Bichejos is a free online price-comparison service for pet products. It helps owners find where a product costs less by comparing listings from retailers such as Amazon and El Corte Inglés, with delivery charges included in the displayed total. The service is available without registration, adds no extra fees, and directs shoppers to the retailer to complete their purchase.

Users can search by product name, brand, or model, or browse the catalogue by animal, product type, and brand. Listings are compared using product barcodes where available, and results are ordered by the total payable, helping shoppers compare like-for-like prices rather than headline prices that exclude shipping. Bichejos reports comparing products across two stores and features a catalogue of more than 90,000 price-compared items.

The range covers supplies for dogs, cats, birds, fish, small pets, reptiles, and horses. Products include food, litter and cleaning supplies, collars and leads, beds, toys, clothing, health items, feeders, aquarium accessories, and other pet equipment.
