I've been shopping Amazon for few years now, & know my way around it...

Pro's
1)Amazon recognizes your using Honey & adds a (cheapest line) at the top above displayed products.

Conns
1)Had to disable & re-enable honey add-on frequently (support instructions)
2)Honey button still wouldn't appear for all items
3)Purposely chose most expensive item out of Amazon results, & Honey=(Best) & didn't see the dozens of stores selling the same for as much as 50% cheaper!
4)Honey didn't distinguish between public pricing & prime membership prices, leaving you to click each to figure out which, by default.

All the above was done while researching multiple items. As well as place the majority of blame as a most likely result of variance between item descriptions!?
