The thing is it is $598.00 two year plan.
And the very moment it changed hands from M1 to you, it's second
hand, you still dare to sell so high?
Outside selling $665 with contract, you selling $650, you think you
are offering a very good deal? I might as well just not smoke for a
day and save up one buying buy NewPaper for 1 week and I will have
the extra 15 to buy new one.
Who knows, you may have did something wrong to the phone so not
happy sell it for 650, and then top up another 15 buy a new
one???
Please do you market research before you attempt to sell. Even if
you go to shops to sell to them, saying it's only 2 days old, you
think they bother?
a certain link below shows you the market price for a second hand
phone re-sell value.
