Someone on my forum snapshotted a popular retailer's products he was interested in and waited for the advertised BF deals - the same products were increased in price by 10% with, you guessed it, a 10% off BF special offer !
It's kidology, sure there may be a few deals around with tat and old stock being shifted at low prices, but no one in their right mind would sell popular products at discounted prices in the run-up to Christmas when stocks are being sold at normal prices - not unless they're in the habit of giving money away.
