I'm not an ESFJ, but I can describe my ESFJ e6w7 so/sp grandma to you (since there are limited ESFJs around here).
- First & foremost, my grandma wants a deal. The price has to be right. She does recognize that quality is worth more, and she will pay more for it. Occasionally she lets her preference for a deal influence her purchasing choices (ie buying something mainly because she has a coupon for it).
- Quality is important. She's really big on comfort also. Convenience is not as important; she'll go out of the way for a deal or something she really wants. She goes for classic, timeless, good quality stuff over novelty stuff, except that....
- She loves gadgets

. I note this with people who have inferior Ne - their iNtuition sometimes manifests as an interest in objects which accomplish practical stuff in an improved way, but what it's accomplishing is not particularly groundbreaking in itself. Sometimes this amounts to frivolous, goofy gadgets which seem more trouble than they are worth. On the other hand, she's always on the lookout for the "new & improved" way, which means she tends to have the latest & greatest when it comes to practical stuff (ie. washing machine).
- She loves home shopping TV, catalogs & buying online. This is because she has specific ideas about what she wants & she can find stuff stores don't carry in them.
- She is not one to browse. She plans ahead & knows exactly what she wants & goes to a specific store for it, or hunts it down online, etc. Once in the store, she generally gets what she wants & then gets out. She often does research beforehand & puts stock in recommendations from "experts" or overall good reviews. If she can't find what she wants, then she tends to hold off shopping for awhile until she can find it, keeping her eyes/ears open in the meantime.
-She likes to stockpile stuff. She has more food, toilet paper, etc, than one person living alone could ever need, and she has multiples of practical items like irons & vacuums.
- She keeps strict track of where her money goes & how much she has spent on what.
- She doesn't really seem to enjoy shopping in itself so much as viewing it as a mission to accomplish getting something she "needs". It really comes off as some survival "scavenging & gathering" tactic.
