I was on an engineering team in college that built full-size racecars (the competition was called Formula SAE). Digikey offered us a 10-15% discount, depending on the parts we were buying, and Mouser offered a 3% discount (at that point, why even bother?). Digikey's discount was easier to use too. Occasionally Mouser had something that Digikey didn't but I tried to order from Digikey as much as possible.
