I try my absolute hardest to not pay full price for anything if I can help it, even if I have to shop several stores in a day to find the cheapest available price. There are times though that I will admit the convenience or urgency factor factors into the equation. You have though laid a bummer on a potential plan to get a new washer, hopefully one of those that use less water, sometime this holiday season when prices drop. (party pooper)
Why's that? Get the washer :D
The idea is to buy stuff for cheap that you absolutely need but don't allow the sales to trick you into buying shit you don't need.
