Just interested on what people's takes on some frequently occurring sales situations are. The first I see a lot is where, say, they're selling a bottle of Powerade for $3 but you can get a pack of three for $8. Do you see it as saving $1 if you buy the pack, or do you see it as saving $5 by not buying more? I always think of Mr Burns' quote in an episode once where he said "hmmm...I'd be happier with a dollar!"
The second scenario is when you see something, let's say toothpaste, on sale for $2 a tube, whereas it's normally $3.30 a tube. Do you go crazy and buy as much as you can, or buy what you think you'll need for the next few weeks/months? I mean, if you go crazy and buy a barrel load, you might see it as long term saving. But if you only buy a few more than what you'd otherwise buy, you could think that the money you save on not buying more could be put to better use (instead of being held up in toothpaste that's not to be used in the next year or so).
Welcome any other 'sales' scenarios.
