I just called (was on hold forever). The 3 main rebates ($170, $140, $200) will all indeed work together. The sales rep said to make copies of the packing form to include in the MIR, and to keep the original. The last rebate, you should call to verify if your school is qulified. Although my school is not on the list (Binghamton University), she said there is no harm in trying because they still might honor it. Hope this helps. Thanks for the deal!
