Help me with Marketing

We are looking for innovative retail promotional ideas for a regional NSW shopping centre. Specifically to promote national events such as Mothers Day and Fathers Day with an objective of driving foot traffic into the centre, in centre sales and growth of customer database. We want to engage the local community with a catchy and interesting promotion rather than the usual 'enter a draw' to win a prize mechanic. Delivery channels for promotion include in centre print ( posters), digital (EDM and digital screens) and social media including FB. Promotional Ideas should be presented with mechanic details and creative approach across delivery channels. Promotional budget is limited and delivery does not stretch to external media channels such as press, TV or radio.
