There are limits! Hit some supermarkets at the right time and it's like the California Gold Rush (on a smaller scale) and you're forced to do the walk of shame to the checkout with a basket/trolley 96% full of mark downs. Glory Days. Sadly you start to recognise the same old 'Gold Rush' faces...
Worse is the garish yellow supermarket price reduction stickers, never get those fvckers off, which can be massively problematic if you've got some snobby punters round gawping in your fridge.
