Tesco stores have some really good prices on Easter goodies - including craft and art sets.
For example, I bought:
pack of coloured feathers for crafting: 17p
pack of easter foam stickers (various shapes - rabbit, chick, eggs etc): 17p
craft chest (tub with paper, googly eyes, pipecleaners, shredded paper, pom poms) :99p
art chest with similar goodies: 99p
paint and glitter pens: about 10 paint pens, 20 glitter glue pens: 99p
easter chick pinata: £5
easter basket: £1
Other similar things were also very competitively priced, like DIY easter cards for 37p per multipack etc.
Worth a look !
In store at Chester HomeStore ... these are nationwide offers though, I think....
