iTalkBB hidden cost

It can be frustrating to follow every steps of a "good deal" and find out some hidden cost (shipping, tax and fee, etc) that breaks the deal. So are there any hidden cost for i Talk BB?

Let's look at the advertised $299/year ibbtalk global unlimited plan. If one actually follows through the registration steps on www.italkbb.com, it would turn out like the following:

There is a $9.99 shipping fee, a $15 device deposit for Linksys SPA-2102 (which we highly recommend over SPA-1001 for reliability), and $35.4 applicable regulatory fees and taxes.

Using promotion code "953110+8991156825" can save you $15 instantly, making the total $344.39, $15 of which would return to you upon service cancelation. -- Scroll your window to the right if your order page shows empty in the amount column. 

There is additional usage charge billed monthly if you make calls to countries that is not covered in the plan or to cellphone numbers in some countries, but this would be unusual. 

Is the $344.39 over the bottom line as a great deal? You decide.
