article: It's enough to pay for a small home extension – and if Jennifer Drew carries on like this, she might well need one. The mother-of-one has saved £17,000 over three years by spending an hour a day searching for deals and coupons. And she has now accumulated so many products and groceries that they fill a whole room of her house as well as her garage. Mrs Drew, 31, is so keen on a bargain she even bags items she does not need and gives them away to friends. Scroll down for video . Mother-of-one Jennifer Drew has saved £17,000 over three years by spending an hour a day searching for deals and coupons . Among the hoard of products – many of which were bought through multi-buy deals – are 20 bottles of mouthwash, 52 bottles of baby lotion and shampoo, and stacks of dog and cat food, even though Mrs Drew and her husband, 33-year-old plasterer Neil, do not have a pet. The frugal English teacher estimates she saves £70 each week on food, and once even managed to get a weekly shop worth £140 for just 29p. Mrs Drew, who uses newspaper coupons as well as voucher websites such as Wowcher and Groupon, said: 'I can't imagine life without coupons and, to be honest, I don't understand why no one else is cashing in. 'Once you get to grips with the process, it's very simple. What people don't realise is that a bit of research can save hundreds of pounds.' The 31-year-old has bagged so many bargains that she has even dedicated the garage at her home in Ashby-de-la-Zouch, Leicestershire, to stockpiling extra products (above) Mrs Drew, pictured with son Nicholas (left), estimates that she saves £70 on her weekly shop by using coupons and money-saving websites - and once managed to buy a week's worth of food for 29p . Mrs Drew's obsession with couponing started when she was pregnant with her son Nicholas, now two. She suffered severe insomnia and while watching TV at night she stumbled across American reality show Extreme Couponing, which follows savvy shoppers as they find bargains. Mrs Drew, from Ashby-de-la-Zouch, Leicestershire, said: 'I thought I'd give it a try. By the time Neil came down for work, I'd saved more money than I'd earn in a full day's pay.' Not long after, Mr Drew was made redundant and, with a new arrival on the way, the couple were facing huge cutbacks. Mrs Drew said that when she began shopping for the baby she would bring home bags 'stuffed to the brim and Neil would look on in horror'. 'He panicked and thought I was spending a fortune but didn't realise how far my coupons had gone,' she said. 'He couldn't believe that I had saved so much money until I showed him the receipt.' She added: 'I get a real buzz every time I save money. It's like an addiction.' Mrs Drew now spends around an hour a day during the week, and three hours on Saturday and Sunday, searching the internet for the best deals. For a few months last year, she ran free classes at her local library and 'fully trained' around 20 people in using coupons.
