Will trade an iPhone 7 PLUS 128Gb Unlocked, for an iphone 8 in Sidney, British Columbia for sale

I have a very good condition unlocked 7 plus with an Apple leather case.
128 gb, with case and accessories. Given these two phones are very similar priced, and I would like to go to the 8 regular iphone or plus again with extra money, let me know what you have to trade me? May sell the 7 plus as well. As noted above the price for it is $650. firm as rock. It's in excellent condition and comes with original box and accessories, in addition to a genuine Apple leather case. It's a black matte iphone. NO lowball crazies please. No paypal, in person local purchases only. Can meet at a public place such as Tim Horton's. No shady deals. Cash only.
