Just picked up this SS13 Balenciaga jacket for the ridiculous price of £39, down from £625.
In the shop I work in, sale items get 'auto-reduced' by some kind of computer algorithm, so stuff just gets cheaper and cheaper if no-one buys it. Sometimes stuff gets buried somewhere, or no-one picks it up for some other reason. I got an ACNE shirt for £9 down from £160 too. I guess retail has the occasional perk.
