not really legal as such but im not sure where else to put this. i bought 2 bras in sainsburys this morning i didnt try them on as dc were with me. anyhow when i got home i realised i picked up the wrong size so went back this afternoon to return them and was told by the store manager who just happened to be at customer services at the time the bras were non returnable. im shocked as m&s etc will return them and when i asked were this policy was written he couldnt tell me. can anyone advise me on sainsburys policy. im counfused.
