For those of you who have a military ID like me, Fort Buchanan, which is around Bayamon, has tax free EVERYTHING. BX, commissary, food court, furniture store, banking, GAS, library, fitness center, bowling alley, etc. etc. Unfortunately, cars don't apply to the tax savings, but luckily, Puerto Rico used cars aren't taxed!!!
There are also children's activities, DOD school, club activities, theater. I'm pretty sure my kids would be able to participate on the various kids activities they have there.
I'm feeling tons more comfortable knowing I have such a great resource at hand. It makes transitioning so much easier.
