Tescos have a range of things in for £1 including,
pack of hairbrush and comb,
150 hair bands,
20 pencils,
20 colouring pencils,
screwdrivers,
bathroom mirrors,
childrens bead sets (ideal for parties)
set of car (ditto)
etc, etc,
Thought the hair bands were a bargain as a pack of 10 can cost £1 - £2.
