Spend a few moments to consider where your project fits in with the business.
Tiny extra costs may not be worth the time or effort to try to reduce. You might spend more money trying to reduce them than the savings in doing so.
Prioritise tasks in terms of your project and also for your organisation. You might have something important for your project to do, but if doing so will delay many other projects even more, maybe you should alter that item to benefit the big picture.
