Having just had requests for websites from some offline clients, and as I'm pressed for time I looked at some of the website templates sites. I found what I was looking for at TM, and as I was about to purchase I spotted the 'coupon code box', so I did a search on Google for 'whatever service' + 'coupon code' and found several sites offering the latest codes. I tried it and got a 30% discount on the price. Well pleased.
So, the lesson is, take a few minutes to search for discounts and you could be surprised at what you could save.
