Do you know this? You have a strange urge to buy things that are on sale, despite you feel that you will never use them at all? And you still buy? I recently discovered how much 3d stuff I have bought over time. First I bought to explore what possibilites exist. I bought tools and items to learn from them.  I liked Avatar a lot. I found some products to make very realistic images, I did not think would be possible at all. Then I got busy to develop tools on my own, but still kept/keep buying things that are on sale. And never used them. Some I think I even did not download at all.
I buy/bought with the bizarre thought of making a gain, even though it just takes money away.
I spend less than a smoker does, but still, I really wonder what that is.
Anyone else suffers from on-sale-addiction =) ?

At least I do not have an ipad or iphone. I guess then I would purchase useless apps ;)
