I had a 15 minute browse in TK Maxx today about 4 o'clock ish and bearing in mind this is in a small little one in Surrey I could have bought
Olive fifties style dress by MCQ by Alexander McQueen £39.99 (down from £400)
Summer evening jacket by Valentino £79.99 (reduced from £700 - ok it was a bit italiano but looked the biz)
Red slim fit Ralph Lauren polo shirt for £16.99
There was a surfeit of DKNY denim jackets and some lovely white short sleeve shirts with bow collar detail by Red or Dead.
If you can save your pennies and wait to buy designer pieces, which of course are random injections into the main stock, then you can snaffle bargins galore.
