Buy the shoes, get the bag free
Now this is the kind of deal I like! If you buy these Gucci-esque mules from Additions Direct for £19 (yes, really, £19), you can get the bag for free. Bag Lady fans will know that the bag is inspired by the cult classic Balenciaga motorcyle bag, but as a freebie, it's far better value than the hundreds you'll pay for the designer version. There are various colours available, and also a pair of knee-high boots for £29 or mid-heel court shoes for £21 that'll snag you a free bag too.
