So hi there...saw your Apple iPad 7s--the unloced ones--up for sale....what would you be asking for them? :)
Rose Gold is my favorite color!
Why, I would have to agree with you...!  How much would you like for the Rose Gold one, or does that one hold special meaning for you...?  :D
I would love to sell the Rose Gold one to you. I am asking $780.00.. For you, I will take $750.00 
Rose Gold is my favorite color, and I wish I had the budget to pay what you're asking!  I desperately need an unlocked Apple iPhone 7, but I am budgeted at approximately $375.  If I asked for the matte black phone, came to you (saving you gas and time), and let you keep the Rose Gold one...would you consider $375?
I would consider selling this phone to you for $550.00.. That is the lowest I can go.. I will also throw in a screen protector and buy you coffee at our local Starbucks. I really do not think you will find a brand new unlocked Iphone this cheap anywhere else. And you can still have the Rose Gold color! 
LOL - You drive a hard bargain!  That coffee absolutely sounds good, as does getting the Rose Gold-colored phone.  You are not kidding that I won't find a better deal for that price!  The original $780 you're asking for is entirely reasonable...and your current offer is even more generous.  I hope you can forgive me for all the barter, here, because this request in no way is an insult...it's simply that I'm forced to dip into reserves here...  I might be able to scrape up enough to counter with $425...  Again, I wish I could go higher...
My final offer is $525.00 and I am unable to go any lower. This phone has a warranty from the manufacturer as well. It is brand new and I'm taking a loss as is.   I will submit the final offer. Maybe you can borrow the extra hundred dollars. I do hope you will be the owner of this rose gold colored Iphone!
