..I don't have your skill and knack at finding stuff but there is a page of John Lewis offers and things like crackers for £2.50, which are half price..(probably from last year..)...

..one thing that is good for young children are jar/hampers, which you can use old ones you have or buy them for around £1 and fill them with lots of small things...hair accessories etc for girls and small cars and models etc for boys..with sweets, marbles and just anything small and they're really nice gifts with bow around the top etc and all sparkled up...and for older people..grandmas, aunts and just generally older neighbours etc...jars of homemade things like chutney, which hardly cost anything, it's just the making of and muffins...there are some really nice muffin cases and boxes on Ebay and just great gifts to make.../again hardly any money at all...
