I wonder too?
My husband is VERY nosey so any time I want something. instead of just telling him I want ________! I find it online, and save it to my favorites, then I rename it like, I WANT, or GOING TO BUY, SAVE FOR THIS! Which it is still a suprise when he does get me something because even though I know its there I don't know when or if he has looked at it or actually make the purchase. This is also great for gift giving ocasions. He asks me what I want I just tell him to check the usual place! lol
