It's finally here again, the much anticipated day that all the stores has been blasting about for weeks now. The day you shouldn't be buying anything.
While the discounts offered might be tempting and today's purpose might be easily discarded in the lure of bright light and huge percentage signs the shops have gracefully made it even easier: the sale started already weeks early and will continue days afterwards. So even if you don't buy anything today there is still time to participate in the fest of consumerism.
Of course it's a good time to once again buy normally priced products. You just need to be careful. The shops have a menacing practice of hiking prices just before the sales so they can show those previously "normal" prices as hugely discounted ones.
Another trick they might use is to bring models specially made for these sales in spotlight. It's harder to compare the previous prices (unlike the regular products as there are multiple price history services available) when it's first time on the shelves.
