Clone di Keepa, attenzione!

Saved me tons of money. It offers more than just amazon price tracker, also suggests free coupons on other sites such as walmart and esty.

This is a 1-to-1 copy of the Keepa.com extension, but with the extra permission of "Access your data for all websites".
This extension will probably turn rogue someday with an update.

exactly what i need. waiting for the right moment saved me quite some money

Access all the websites you visit instead of just Amazon websites, so they track all your web activities and sell your data.
