Yes, they do price adjustment. I think it's 14 days but you might want to call a store to make sure.
Just read everyone's comment regarding price adjustment. Thanks for your input. No ajustment..? Then fine. It's by my office so if I see my dress I'll just buy it and return the one I have at home.. :)
My boyfriend got a heap of stuff from suits to jumpers, i got a brown leather jacket and i got my little brother shorts for like AUD$16 each, It was crazy in there people were everywhere the clothes were everywhere and the line was so long for the women change room. This was in Hong Kong. I will have to say i enjoyed the H&M sale much better for accessories that was fun! xox
