I agree. Of all 3rd party top-up sites for US providers callingmart is the cheapest with the lowest fees right now. I normally delete spam from/for these agencies here, as they are overpriced and they try to use this WIKI for promotion. But your recommendation about callingmart is totally all right.

Given the fact, that callingmart actually sells top-ups below the price of the operator (like T-Mobile), which is very rare in the world, we should mention them somewhere in the article.
