If you follow us on Twitter (@prepressperth) you will notice that we are running a weekly competition throughout September to celebrate the launch of our promotional mousemat.

A new competition theme will be announced each week. Each competition (apart from the first one) will open on Monday at noon and close on Friday at noon (BST). The winner will be announced by 4 pm each Friday.

The first theme is great public misspellings and it closes at noon on Friday 10 September.

To enter you have to tweet your response to our theme. Your tweets must be tagged with #prepresscomp for them to be entered into the competition. Anyone (except our employees) can enter but you have to do it via Twitter.

The tweeter of the best tweet (as judged by our management team) will receive £20 worth of Amazon vouchers, which we will send via email to the winner.

Get started here. Remember the tag! #prepresscomp
