I bought a 5AH battery for my Ego Electric Mower at Bryant's Ace Hardware in Oakhurst Ca. Price was $322.00 including tax. Two months later, I went on line to Amazon and bought the SAME 5AH battery for $75.00 including tax and shipping!!! This is a $247.00 difference in pricing or over 400% percent greater at Bryant's ACE Hardware. Mariposa Foster Ace Hardware had the same outrageous $322.00 pricing with tax. Called ACE Corporate office and they said the recommended selling price for all stores was $299.00. DO NOT buy Ego replacement batteries from Ace Hardware or you will be massively ripped off!!!! Buy them on Amazon. Ace really needs to check their pricing and be more competitive!!!!! I don't like being ripped off, and I am sure you do NOT either!!! Mark F.
