Yes.... the sales people will tell you about the credit and it sounds really good especially if you were counting on that amount to help with the down payment ... however since they cannot see your return or possibly know how the credit will actually effect you they cannot promise you anything.
Review the form 1040 page 2 lines 47 - 56 ... and especially line 53 & the credit form 5695 ... to see how that affected your return.
