I am gettting the Dark Grey as part of the promo for buying the s7 (http://www.amazon.com/Samsung-Gear-S2-Smartwatch-Dark/dp/B015JQ62RY)I really want the Classic (http://www.amazon.com/Samsung-Gear-S2-Smartwatch-Classic/dp/B015JQ60NA)The difference in price is $50. Does anyone here that has the Classic want to swap? (with me paying the difference in $$$)Or is there any store that would let me swap and just pay the price difference?
