Black market counterfeit DVDs and CDs worth at least £2 million were seized by police and trading standard investigators following raids on houses in Tamworth, Stafford, Stone and West Bromwich.
As part of Operation Carter, 45,000 discs worth £1.35 million to the entertainment industry were recovered at a Cannock car boot sale on Sunday.
Yesterday police with a search warrant raided a house in Tamworth and found copying equipment and thousands of discs worth £300,000-400,000.
On September 25, also part of the operation, police and investigators stopped a van in the Essington area of Walsall and found thousands of discs with a value of £316,000.
Among some of the seized DVDs were copies of the latest Wallace and Gromit - Curse of the Were-Rabbit - which has enjoyed record box office takings in cinemas.
Det Sgt Garry Helsby of Watling Police, Cannock, said: "This operation has been ongoing since August and it has been very successful. We have seized stuff with the value to the retail market of £2million.
"It is part of an ongoing operation and people at car boot sales who think they can sell these CDs and DVDs and think they can get away with it should be warned we will pay them a visit." Also taking part in the Operation Carter apart from police and trading standard officers were officials from the Entertainment Leisure Software and Publishers' Association and The Federation Against Copyright theft.
Raids were also carried out at Derrington, near Stafford, where £18,000 in cash and £ 8,000 cigarettes were recovered. Blank DVDs and copied DVDs and £416 in cash were seized in West Bromwich.
At one of the biggest car boot sales in Staffordshire at Wellington Drive, Cannock police said store holders fled their pitches "in all directions, many just abandoning trays of the pirated goods rather than be caught."
