I see how you get that impression from my colorful, limited, example but,
no, I'm speaking of products in general because, while people are sanguine
about 'sales', 'special offers' and 'rebates', they generally expect price
stability, or feel something's amiss.
My example was just one embodiment but the general effect doesn't need a
purchase. Say someone is 'thinking' about buying a computer but it's one
price this week, higher a month later, and then something else a month
after that. Bouncing prices on something not even bought won't sit any
better than the 'hooked' example and the prospective buyer would be
screaming "well, if it's a 'temporary' price then why the hell didn't you
SAY so?" and it doesn't take much imagination to envision the 'sneaky
motives' consumers would ascribe to the price changes.
A rebate "says so."
That's easy for *you* to say, when you don't have to do it.
