There is a change at NACO and a the minimum sales for agents has now been increased from $500/yr to $5,000/yr.
As a result many of your smaller FBO's will probably no longer be chart agents.
For the charts that you use routinely the easiest way is to buy them from the source:

The new charts arrive just before the old one expires. Totally easy and as low or lower cost than commercial sites.
