Clintons are currently clearing last years halloween costumes. The one's I saw were £3.49 from £6.99. They had Witch, Vampire, Pumpkin, Witch Fairy and Spider in various childrens sizes. I thought it was a good price compared to what I paid last year.
The staff told me once these were gone they would put out new stock at full price.
Both stores in Cheltenham had these in stock but weren't that many so may vary regionally as depends on what they had left from last year.
Sorry had a look on google and can't find any pictures of the costumes that I saw not that I know how to add a picture yet.
Hope thats ok as is my first deal.
