Design a Flyer!!!

Want a 50% OFF across all range flyer design for a shoe company. Flyers are to be hand distributed so should be eye catching with fonts easily readable from a distance. Attached is the logo of the company and the address is as follows:

Walk
111 Oxford Street
London
W1D 2HW

Catchy tagline required emphasising 50% OFF. Need this asap so preference will be given to people who can deliver it with few hours time. Attached couple of examples as well.

Kindly send across your drafts or any ideas and best will be chosen.

Regards
