i've never compared final price to retail simply because the retail its way off my wallet and its silly. what difference will make if it was retailed for 150k or 50k and i bought it for 10k, no difference to me. 10k its what i paid and thats it. i don't need benchmark to help me justify something i like or not.
there its huge amount of sample sale garments on yahoo/rakuten. all marked with red pencil(instruction label) are from sample sale.
