The show sees sellers and inventors given 90 seconds to pitch their product in the hope of securing a potentially life-changing order with national retailers Amazon Launchpad, Lakeland and JML
Moving to a peak time slot, Rylan Clark-Neal will host a four-part Christmas themed version this festive season.
In each episode, the sellers demonstrate their product to an audience of 100 potential customers who each hold a voting handset.
If the innovators manage to impress at least one of the 100 shoppers, they get a chance to pitch to a panel of big-name retailers who can make a potentially life-changing bulk order; if not they are spun off the revolving stage, making way for the next seller.
In the first episode (November 28), a retired couple from Yorkshire have sunk their life-savings into a cafetière with a twist.
Bridget from Newcastle hopes to tickle the taste buds with her marmalade that makes the perfect Christmas cocktail.
A nine-year-old girl hopes her new card game will make the perfect stocking filler.
And it's the last chance for musical director Roger and his innovative roasting tin.
Episodes air Thursday nights at 8PM on Channel 4 and are available to watch online via All4.
Last series saw a number of sellers successfully have orders placed by the retailers, including Sylvia from Sutton whose nifty solution for tired, sore feet scooped an order with a retail value of £225,175.
Rylan Clark-Neal said: “I love nothing more than always trying to get my hands on the latest products, so now I can’t wait to meet these fantastic inventors who have designed and developed some amazing items and see how many of our audience want to buy it now!”
Tim Hancock, Commissioning Editor added: “We loved seeing ordinary people with a passion for their innovations succeed in the daytime series of Buy It Now.
"The new, supercharged, peak-time series with Rylan promises festive fun and Christmas contraptions that are sure to surprise and delight.”
Head of Unscripted, Darrell Olsen at programme makers Studio Lambert North said: “This is an incredible opportunity for anyone out there with a product, no matter how big or small to showcase this to real customers, and potentially have the opportunity to supersize their sales with life-changing orders from our high street and online retailers.”
Creative Director of Studio Lambert, Tim Harcourt added: “This fun series shines a light on two great British characteristics; our high regard for creative, commercial endeavour and our guilty love of the impulsive purchase.
