Description: Adds an inline box to Amazon product pages and displays price history data for several seller types (e.g., Amazon, 3rd party). It is similar to The Camelizer, but I believe it is slightly better since the data is graphed/rendered directly on each product page.
Brave has Honey built in already, which does what you seem to want. Is Keepa better?
Much better. Keepa has product price history, shares that interactive graph with people visiting the product page. Shows all the prices over time. Its not a coupon plugin, but a price plugin that shows how prices vary. Must have plugin. thanks, works on Mozilla and Chrome. is there a work around to install it?
