I missed out on this deal yesterday and was disappointed because I wanted to pickup a 4.0ah battery, why not get it for cheap and a free blower. Anyway deal is back:
Home Depot: $69.99 overstock
Google Express: $69.99 apply 20% for new customers (create new account or use an existing google account no signed up for google express) AND if you have the Amex offer $20 off $60 on Google Express you should be able to get it down to $40ish (worked for me).
$69.99 - 20% = ~55.97+ tax (high enough rate) to get over $60 to end up paying about $40
