4. Sale

Is this the cheapest price I can find?
Is there a lower cost version with less features or add-ons?
Can I negotiate a cheaper price?
Is there an offer, sale, promotion or voucher to allow me to get this cheaper?
Is it cheaper to buy offline rather than online?

Asking these questions is the first step to making sure that if you are going to make a purchase that you do not pay over the odds. You want to pay the least amount of money with the most possible benefit.
