At least you can vend. My idiot mom, bought a mouse with out a scroll wheel.
stressed I'm going to assume that you have a small screen, if you have to use a scroll wheel. But even so, the scroll bar at the right works just fine. I used it before I got my mouse with scroll wheel.
Unless you're using a non-optical mouse. Those get stuck all the time and often don't move fast enough for you to use the scroll bar and vend.
The number one rule of having your parents buy things for you: Go with them.
