Was very hopeful about this site. I did not cease disappointing; 1. With ought calling or emailing or texting me to say - "Hey we are going to be late" , they waited for me to call to follow up after 3.5 hours waiting. (That's 1.5 hours past the delivery window they offered) 2. Once the technician arrived he was very professional. However the "Diehard" brand battery I thought I purchased was not what I received. The tech says it happens adn I should complain totes company. 3. 1-800-battery.com has yet to respond to my two emails asking for the battery to be replaced.
