I can relate to both but I think I am more towards the maximiser. When I read Rubin's book I immediately knew my DH was a satisficer. It certainly has a lot going for it - he is also a low research guy ( for purchasing) - and the combination saves him heaps of time and angst.
OTOH I am a researcher to the point of over research (good thing my day job includes research!). Unlike Marley, as a student I would enjoy the research and not really feel it was like work until the rubber hit the road and I had to actually write something (which usually mention that you had to decide on a position, which is the hard part for me).
Like Manidipa I have champagne tastes and a teetotal budget. And I am picky when it comes to fashion. Totally maximiser. And these combine badly with not likely shopping overly much and getting very easily tired out by it.
When it comes to handed down and gifted items I am much more of a satisficer. I keep quite a few of those, though I wouldn't have necessarily have purchsed them myself. Sometimes recently, when I have walked out of yet another shop empty handed, I have had the thought that if somebody gave me something from the shop, I would be quite happy wearing at least half of the options there!!
But if I only plan to buy, say, _one_ casual sweater for the winter, which is my usual plan - then I want it to tick all the boxes. And I often find myself walking out just not buying. (Because I am such an under buyer)
Conversely when we bought our house last year, we bought almost the first house we looked at and at put the offer in before I had even seen it! ( I told DH I trusted him, and had seen the online pics) The context is that we had been watching the market in our area for a few months, knew houses were getting snapped up very soon after they went for sale, and generally we knew about what we could get for what we could afford. And So the first house that was available and met our needs (and many in the price range didn't), we just bought!! Some people couldn't believe that we were that quick.
Afterwards I said to DH, what if something even better comes up and we'll regret buying now. He said, very wisely: just stop looking. And we are indeed content!
