Always do that math!!! Saving money is key. Note that jacking up prices and putting them on continuous sale and having the price be at or above prices elsewhere isn't really a sale. But some suckers get pulled in by that 25% off figure and don't do the math. Then they pay. Keep in mind this really only applies for like for like. I mean, if you buy, say, a good name brand part, you can't compare it to another, perhaps lesser brand/quality part. You would expect to pay less for the lesser quality. But you never know. Keep your eyes open and do the math.
(and who said you'd never use that math sh*t you leanred in school, am I right?)
