IKEA are giving away FREE ice creams or hot dogs when you fill in their survey. Just follow the link and enter a number from 1 to 100 to get started.
Click 'GET FREEBIE' and when asked for the Project Number type a number between 1 and 100. You will then have to answer a number of questions about IKEA. Once you have finished the survey you will be asked for your email address. This is so they can email you a voucher for your free ice cream or hot dog.
The survey does take a few minutes to fill in, so make sure you do it when you've got some spare time.
