I WILL agree with zip on "Play your cards right, and you don't have to spend money like crazy." However, his view of playing them right, and the right view of playing them right, are 2 different views.
IF you play your cards right, means that you buy a token gift that would go into the blue bag, you won't have to spend money as often pleasing her, because that one gift will cover you for awhile1. Not saying that you don't ever buy her anything again, but you will not be required to match the level of it for a bit2. Another example of playing your cards right is getting her what she hinted at without having to get her to repeat it (or getting the scoop from a gf).
1. that's for you to figure out on your own, as to when the time has expired. We can't (and won't!) tell you everything.
