Advance Auto has the Peak 900 Amp Jumpstarter http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/produ... on sale for $79.99. Add filler item (I used 312114.3 which was .29) to get the price over $80. Apply promo code RAF51112 which takes $30 off purchases over $80. That knocks the price down to $50.28. Next, submit the rebate for $20 off (Offer Code: AAP-10023) and you get this jumpstarter for $30.28.
Thanks OP. I've ben waiting for this rebate. My old Vector Jump Start no longer works. The SLA battery is OK, but the electronics are messed up. This is the same or less than replacing the battery inside.
