FAQ
What can CartGenie do?
CartGenie submits your shopping request and your selected signed-in Amazon sites to an InfiniSynapse agent. The agent uses your current Chrome browser to visit those sites, compare identical and similar products, read reviews, analyze complaints, check shipping and returns, and add the best match to your cart automatically. It runs unattended: sites that are not signed in are skipped and explained in the report.
Will it pay or place orders automatically?
No. CartGenie only searches, compares prices, reads reviews, filters products and adds items to your cart. It never starts checkout, never submits orders and never pays.
Which Amazon sites are supported?
CartGenie supports Amazon.com (US), Amazon.co.uk (UK), Amazon.de (Germany), Amazon.co.jp (Japan), Amazon.ca (Canada) and Amazon.fr (France). Select the sites you are signed in to and it can cross-compare prices between them.
