yea, they obviously make a profit on it because it results in people buying more stuff. but in my situation it saves me money I'm pretty sure. just recently I bought some breadboards and tweezers for electronics projects and some rubber feet thingys for my keyboard. I would've bought them elsewhere if amazon didn't exist so I saved on shipping this way. and unlike what others here have said, things always arrive on time or earlier. maybe that's just a Germany thing tho
