What are the "yellow boxes" that this song lyrics refer to (and what does 160 quid have to do with it)?

I love the song Full Circle by Good Health Good Wealth, but don't understand part of the lyrics in bold: >Answers on a postcard When is it okay to drive in a bus lane? **And what about those yellow boxes?** **'Cause I'm a hundred and sixty quid down and I can't work out if there's any consistency there** Initially i thought they were talking about men's boxers before realising he says boxes lol. What does it mean and what does 160 quid have to do with it? Full lyrics: [https://genius.com/Good-health-good-wealth-full-circle-lyrics](https://genius.com/Good-health-good-wealth-full-circle-lyrics)
