So yes you can come back in for the difference. The only thing is it has to be with the current sale price. Also at any time you don't wont the ITC you can return it for a refund. Most of are tools have better warranty's then sears. And almost all Pittsburg tools have a lifetime guarantee. I always tell people to get an extended warranty on things we offer them on for the purpose of this is mass produced and every so often it has a manufacturer defect. And one last thing as long as you have your receipt and its under 90 days you can return it for a full refund with no hassle. Hope this info helps. Please feel free to ask about anything. Don't forget the big tent sale in June so get your ITC before then so you can get thos prices the day before the sale.
