PriceLess - Price History & Coupons 作者： PriceLess

The PriceLess addon will add a price trends graph on the popular sites GearBest, BangGood and IHerb, with lots of sites to come in the near future.
The price trends graph will allow you to see price drops or rises, and make an educated decision whether to wait a little for the price drop, saving you money.

In addition to the price trends graph, we've also added a Coupon section, so that you can see if the product has coupon, lowering its price even further!
No coupon found? You can request one, and we'll do our best to provide one for you.

This addon works best when there are a lot of active users: Since we measure the price when a user enter a product page, the more users there are, the more info we have, and the more updated it is.

PriceLess is of course free, and is maintained and developed regularly, so stay tuned for new features and improvements!

Note to addon developers: All of the code used in creating this addon is proprietary to PriceLess, aside from open sourced 3rd party libraries used.
