I just (about an hour ago) bought 2 Duracell 27 AMG batteries at Batteries Plus. They were $225 less 10%. Supposed to be great batteries but time will tell.
Preface: I promise I’m not a member of the Walton Family! Just an FYI: for those saying they can’t purchase at Sams Club they are running a promo offering $30.00 off 1st purchase after buying $45.00 membership.
