COTD Mobile app - download and use it to make your purchase with 5% off code
Basically, Catch of the Day has a new mobile app, which you can download via itunes.
As an incentive to get you using the app, if you enter the code:
at checkout, you will receive 5% off your purchase.
I believe it will only work if you use the app.
If anyone has tried otherwise, please share :)
