Warrants were executed in Wigan by police on April 13 following shop raids in Chorley and Preston.
The first was at 10.20pm on March 21 at the Co-op in Granton Walk, Preston, when a large quantity of cigarettes and cash were stolen.
Money and tobacco was again taken in an April 11 robbery at the Co-op in Chorley Old Road, Whittle-le-Woods.
Three men have since appeared before Preston justices charged with robbery, false imprisonment and possessing an offensive weapon in a public place;
They are: Daniel Holding, 32, of Arley Close, Aspull; Daniel Lewis, 34, of Battersby Street, Ince; and Matthew Lowe, 34, of Chatham Street, Ince.
A 43-year-old Wigan woman was arrested on suspicion of handling stolen goods, perverting the course of justice and conspiracy to commit robbery, and a 53-year-old Wigan man was arrested on suspicion of robbery. Both were released under investigation pending further inquiries.
