KayBea is right - it's rubbish couponing in the UK compared to the US. There are too many reatrictions over here to make much of a difference. I'm not sure if you're on Twitter, but I follow Jordon Cox (he's a young guy who has been in the news a few times for his fantastic savings!). He goes by @couponshopuk - he also has a facebook page, but I'm not on facebook so can't help you there. I'm sure Google would help you out
He gives some fab tips - the best one so far is to grab loads of the free supermarket magazines when they're available as they usually have coupons in them. I got soooooo many Maggi recipe mixes for 15p each a few months ago because of a coupon in the Tesco magazines
Also got a free four-pack of Coors light as part of a promotion he tweeted about.
I'm an Aldi shopper too and on the last Thursday of every month, they have a £5 voucher in the Daily Mirror. I do my shopping every Thursday and the coupons run from Thursday til Thursday. I buy two papers, use one coupon the same day, one the week after and voila! £10 saved! (Or two free packs of nappies, depends how you look at it
)
Also, get the Hot UK Deals app on your phone - it's brilliant. Also sign up for something like Topcashback if you can. I made £80 just for signing up for my home contents insurance - well worth doing.
