I mean if we're talking just straight math, even if you don't use the trick to keep your unlimited and buy on subsidy, why wouldn't you just add a line to the nationwide share plan or whatever it's called for $9.99 + approximately 8% in taxes, whatever... buy it on contract, $10.79*24 months =$258.96+$200 = $458.96 total price, cheaper than the outright or the EFT+subsidy and you have a spare line available for whatever in the future, like another off-cycle upgrade. You can put a dumb phone on it and have it as an emergency in the glove box phone, whatever.
Buying it outright is the 2nd most expensive way you can do it, if all you're trying to do is keep unlimited. The most expensive is buying it outright on their finance plan with the $2 charge 12 times adding $24 to the full price amount. 3rd is obviously paying subsidy and the full EFT while losing unlimited data and paying more per month (though of course, the EFT would go down by approximately $120 if you waited a year to upgrade and for some reason cancelled... not sure why this would be the plan), 4th is adding a line, but the cheapest, if it's an option is using the unlimited data retention method and upgrading, etc.
Aside from the taxes and fees (which ranges from $3 - 7), there is upgrade fee of $30 or activation fee of $36. The activation fee will be refunded if you cancel service within 3 days, as in the etf method. I did have a csr try to argue with me that the etf fee wasn't refundable under any circumstances. After I pointed out the website and receipt stating so, the csr reluctantly agreed to honor their written policy. Anyways, I digress. Counting on the lower end, $3 taxes and fees for 24 months plus upgrade fee would be $342 for a basic line, compared to the $350 etf, plus $5 one days usage charge. Obviously, the more the taxes and fees are, the more financially feasible the etf method is.
