Sports socks - three pairs for a pound!
"Sports socks - three pairs for a pound," is a well worn sales cry at the famous Barras market.
Soon it might be joined by another plaintive howl. "Get your season tickets here, going cheap, no reasonable offer refused."
The Old Firm are currently trying to entice punters to part with their hard earned cash, offering special deals on season tickets.
In the wake of the English Premier league's snub to the Glasgow pair, times are hard and liable to get harder as far as extra revenue raising goes.
The spectre of falling crowds and income is a real and live issue for Celtic and Rangers both.
With Scottish coefficients likely to change in the near future because of poor European performances, the Old Firm duo could find their road to Champions League football much rockier than in the past.
Then a vicious circle could ensue: less chance of Champions League action, less chance of selling the season books in the previous vast numbers, less chance of attracting the quality of player to ensure Champions League participation.
The question may be, have Celtic and Rangers peaked, and are their great days behind them?
Suddenly, what many in the SPL regarded as bumptious Old Firm whining that they were too big for the domestic game and needed to swim with bigger fish in a bigger pond, has been drowned out, leaving them to flounder in the shallows of the Scottish game for the foreseeable future.
Indeed, it may be back to the future for both clubs. While flogging their season tickets at the Barras may be an unlikely prospect, both seem likely to face a future of reduced income from that source.
And they will have to explore better marketing techniques or reduced admission prices, if they are to maintain the size of crowds they've become accustomed to.
Simple supply and demand economics are at play here. Too many seats for sale, not enough demand to buy them.
So, sports socks three for a pound anyone? The customer is now king, and his or her money cannot be taken for granted in the current economic climate.
Reduced income equals reduced wages, equals reduced quality. And while other SPL clubs face similar problems, none have built their supporter base anywhere as high as the Old Firm. So there is much further to fall for the great Glasgow rivals.
All of which could be good news for the rest of the SPL.
Managers like Craig Levein, John Hughes and Mark McGhee would be delighted to have the problems of their Old Firm counterparts.
These guys and the rest of the SPL bosses can only dream of being able to pay 10 and 12 grand a week to players, and yet this season in particular, as one half of the Old Firm cannot and the other half will not pay to bring in the quality of player of yesteryear, the gap between Celtic and Rangers and the rest looks much less daunting than in the past.
SPL chief executive Neil Doncaster has said any change in the top flight must benefit all clubs and not just one or two interests. He is right of course, and the game needs to look afresh, and collectively, at how it sells what is still potentially a very fine 'product'. (how I hate that word when applied to the beautiful game).
With our two football behemoths suddenly facing the kind of problems that the rest of the SPL have been beset with, sympathy for their plight is likely to be limited.
Indeed those who have been told constantly that without the Old Firm they would be like the League of Wales, may now adopt a bolder and harder nosed approach to dealings with them, in order to benefit the many, not the few.
With winter's chill winds approaching, it'll need something special to entice missing fans back to Ibrox and Celtic Park. Reduced prices will help, and so will a cosy pair of socks for those cold Saturday afternoons.
They're going cheap at the Barras, apparently.
