Love the idea but feel uncomfortable giving such a young company the ability to read all my email <i>and</i> also send messages on my behalf.<p>Would much prefer if they supported the option to forward relevant messages to them, TripIt style. One can always create auto-forwarding filters for, say, all Amazon order confirmations.
Slice (<a href="https://www.slice.com/" rel="nofollow">https://www.slice.com/</a>) is a more mature startup that does the same thing. It was recently acquired by Rakuten.
*>"The startup has a small, undisclosed amount of friends and family funding and isn’t actively fundraising."<p>Read: "we are open to accepting money at a very favorable valuation now that you've read this on TC." They're obviously in a position of strength here, but this seems pretty transparent.
We've been working with these guys for several months now and the savings are pretty massive. On Amazon, in our experience, about 5-10% of purchases will qualify for a refund. It's a set-and-forget type service, so you literally don't have to do anything after signing up.
The service is brilliant. It's a set it and forget it app which has already sent me four refunds. I recommend it to all my friends, especially those that frequently shop online or use Amazon Prime.
