This is a pretty simple meaning, and it kind of fits along with the idea that Paul puts whatever words that sound right in with the melody. What sticks out to me are the "bicycles for two", "sleeping bags for two", "broken hearted jubilee". It has always struck me as a sad lost love song. I look at the "buy, buy says the sign in the shop window" as when you're in love together you buy things for the both of you, things that mean something to the both of you. And the "why, why, says the junk in the yard" is post-relationship when you have no use for all that stuff anymore.
