If you find out when your supermarket has its delivery of toilet paper (and other paper products) go on the day and any palets that are damaged and by association the wrapping on the paper products ripped etc, they're sold off we got 12 rolls for �1 work it out for yourself!
Another tip about toilet paper- never buy blue toilet paper- it costs more to produce than any other colour and the way the manufacturers con you on this is to make the cardboard holder bigger making the roll look the same size!!
To prove it get a holder from a blue roll and one from a white paper role- the white one will fit inside the blue one!
