NNBM - put to the test

I'm 14 days into NNBM.  Almost half way through.  The problem is that I haven't ventured anywhere near a bookstore, so I haven't actually had to test my sense of resolve. However, a challenge has just arisen. The need for a birthday gift of the certificate variety.  Will I be able to go into a store, buy something for someone else and not come out with something for myself?

Additionally, one of my favorite field trips is Barnes and Noble with a cafe.  Get a new book, then go to the cafe, order a latte and enjoy the first couple chapters of the new book. I was really looking forward to that post Lent - but then I had to go and chose April to be NNBM - deprive myself of two things I love at once. Brilliant Fat Girl. Just Brilliant.
