Depends what you mean by "serious". ;) I often put things in my wishlist so I can find them again, in a sort of "may be useful one day" kind of way. I wouldn't necessarily buy one of them immediately just because it went on sale; it would depend on other factors. However, if I get a coupon or something that I feel like 'spending', then my wishlist is where I'm going to go to choose what to buy. Some products in there are never going to be bought, however. As an example, I have two versions of one product in my wishlist - the basic one, and the all-singing version. I'll choose which one to buy when the time comes and delete the other. And for some products, I eventually realise that I'll never actually use whatever it is and delete it from the wishlist un-bought. HTH
