I now wanted to hand in my 4 full booklets of stickers and 2 of them has black stickers from Spar Queens Corner at Spar Mountain View and now I hear they do not accept these stickers for the money I have spent.This is *********! How can all my slips be taken in exchange for black stickers which are not accepted?
