EDIT: It would be perfect to be able to do a cash deposit in a location nearby. Now bitinstant have deposits through Walmart, CVS and 7-11 but none of them are working in Puerto Rico.
Looks like Walmart will work using this method:
Please please! Do something so that i can make a cash deposit in Puerto Rico. We are a commonwealth of United States. There are walmarts here but Zip zap says that there are no deposit locations in my territory.
Just choose any Walmart in the states, and bring it to a Walmart in Puerto Rico, should work fine.
