Retail is only $500, unless you're counting tax.
Don't forget to count tax on the $199 as well if you buy it with contract.
Add $35 for activation fee.
Add $200 for breaking ETF.
Add one month of service = $69.99 + $10 + ~$5 in fees and tax.
= $220~ + $35 + $200 + $85 = $540
Not worth the hassle IMO.
Where do you see the full retail is $500? Everything I have read says it is $550. $200 instant savings (per the premiere email fine print), + $150 upgrade discount, + $200 new customer price = $550.
Anyway, there is an activation fee and tax no matter how or where I buy them. It's not like it's tax free if I pay full retail, and Sprint has been pretty adamant that there will be activation fees on every device now.
As for the plan, it would be a family plan, probably with 4 lines, but at least 3.
So, per Sprint's website, it would be $130 for the plan, plus $40 for the 2 extra lines, plus $40 for the premium data fees. So the total would be $210 for the plan for a month, plus $800 for the phones, and $800 for the ETF fees. That would leave me with 4 devices, no contract extensions.
So the total would be $1810 plus tax.
If I do it the "normal" way, I would pay $200 for the device on the main line, and then $550 for each of the 3 secondary lines. That would be $1850 total, and I would be under contract for 2 years on the main line.
If I were to take the upgrade on the main line, and do the new account thing for the other 3 lines, I would be looking at $800 for devices, $600 in ETF fees, and $180 for the extra plan ($130 for the plan + $20 extra line, and $30 for the 3 premium data fees.) So that would be a grand total of $1580, and I would have a 2 year contract on the main line.
I think I am liking either the first option (no contract extensions) or the last option (cheapest and get the phone early through premiere).
