I didnt grow up poor, and I have made "tech money" my entire career - but I very often check cent/oz on products - because I dont like being cheated at that level...
HOWEVER.
Annecdote:
I was at dinner in SF - and we were at a very nice restaurant, nice wine, food etc. My buddy was kvetching over buying this watch, which was something like $200 and was talking about how he wasnt sure if it was worth it...
I looked at him and said "We are spending over $200 on this bottle of wine tonight without blinking, which will be gone in moments - and youre kvetching over a $200 watch which will be around forever?"

Expense-perspective is something to reflect on.
