This is you donating to the non-profit. You get the tax break, the company does not. I'm so sick of this misinformation because nobody actually donates on their own, which is why non-profits partner with companies for fundraising.
It's on your receipt, you get the tax break. As simple as that.
Do you have a Microcenter near you? Their prices are usually the best I've found. They have some shippable gaming laptops that just barely miss the specs or price target you have from what I saw but it's worth looking into.
