WHSmith in Wisbech opened late this morning (Tuesday) due to flooding in the store.
Staff came in for the second time this week to find water over most of the floor in the town centre shop.
Luckily none of the stock was damaged and the water was limited to the carpet.
The store opened at around 9.30am, one hour later than normal, to allow staff time to clear up the water. The shop also flooded on Saturday, with the water coming up through the floor rather than down through the roof.
Staff are hoping the cause can be found out so it does not keep happening.
