Perhaps if you’re buying something as an investment, and are trying to predict the future price—but even then, the price in the past doesn’t tell you much.
- Essentials: Things that are necessary to get irrespective of price variation at that moment.
- Luxury: This category could have something which might improve quality of life or something I might have fancied after seeing some marketing about it or reading some reviews about it.
It is for the Luxury category I care about the best price. These things I might not need immediately but investing in them at best price might improve my quality of life with not hitting my pocket hard.
My recent such shopping was getting an Apple Watch for my wife as a birthday present (still a surprise for her). To get that I found that I evaluated that I do not need to pay for Apple Watch 6 or 7 but an SE version would be a good one at cheaper price with all valuable features needed. Now there was a deal which allowed me get the watch for 391 SGD which is 460 SGD even with a Black Friday sale today. I think it was a good bargain and over a period these bargains might add to good saving.
Personally I’m offended by false availability and delivery dates. For example, that time when Amazon said it would be here tomorrow and it was really a week and a half. That’s the difference between getting it online or going to Target.
On one level you want to know you are not being lied to as a function of the relationship.
If Product A cost $500 at manufacture suggested retail price, was currently on sale for $450 but was sold at $360 a week before that, wouldn't you want that information to make a better informed decision?
