Only 2 days (counting today) left and I'm under budget.
$19.88 for 9 books (one was a 5 book omnibus). $20/month
I probably could have done better.
Only 5 were wishlist books. ^^; But, that's better than I did in both November and December.
I am currently reading one of the books I bought that was not on my wishlist, it was a sale + coupon and am thus far satisfied with my purchase.
I do fear I might go overbudget this month is someone publicly shares a 75% code though. O_O
I was lucky enough to get a few 45%s and a 55% which I am saving to use in February to not go over budget.

I am hoping for a couple of higher codes, but I think I'm okay with these.
