I don't know if anyone else has noticed this paradox.
Counter-intuitively I find that at big sale times, my wishlist actually substantially increases in size.
To ensure I am getting the best deal for me, I wishlist lots of extra items for comparison, to make sure I am purchasing the best deal that appeals to me.
Now up from less than a dozen items, it is well over 40 items!
Still, it isn't really a problem, just an oddity, as you think your wishlist would shrink in size.
