the key to get this type of 10p deals is to fins the product the the correct item code. then they will scan at this price. display may have a different price but it doesn't matter if the item code matches with whats shown below.
i work in b&m ... so, i can confirm that :-)
Wooden Clothes Pegs 60pk - display shelf code : 289798
Super Strong Clothes Pegs 40pk - display shelf code : 289795
price tag should have the above item codes to scan at 10p
