Angie talks about when it makes sense to stray from PPP purchasing principle.

Somehow, I can't seem to start compromising, and I'm not sure where to start if I do. At this point, I'm opting out of various social events because I don't have appropriate clothing, but there's no deadline.

Budget isn't really a limitation right now. I want one and only one coat, so it needs to be a perfect trench, and if that's a full price Burberry, meh, whatever, I'd swallow hard but immediately be wearing it every day so its PPW would be lower than that of a sales-price coat in the multi-coat repertoire of someone who needs variety. Maybe I should push myself into b&m discount houses and see if I get lucky with an coat that's close enough.

How do you make your second-best purchasing choices, and how do you decide where to compromise?
