Yes, I have a limit, but it's partly a personal limit. I always look at the price of items because I work for my $$ and for the effort and time I put in to make my $$ I refuse to be "wasteful" with my money.
But ultimately "waste" becomes a very subjective word. I know I purchase lots of things that seem very wasteful to other people. That's also why I tend to shop by myself for some items (or I go with specific friends for that shopping trip - I too do not like the comments). :shame:
With that said, my limit becomes more of a logic limit for me. If the item is worth that much $$ (IMO), then I'll purchase it. Otherwise, I would feel I was tricked into wasting my $$.
ITA. I also don't like the comments. I also shop by myself and that to me, is so much more funner. I don't need people around me that I'm forced to follow and wait for them to do their shopping, it's a lot less hassle without them in the way.
But I also watch what I buy. I plan on stopping soon after this year. It's going to be hard, but in the long run I'll be glad I did.
