Hi
Apple's return policy may vary by country. In the US, it allows for products to be returned for a refund or exchange within 14 days of purchase. Your purchase is well beyond this time limit.
In some countries (including the US), Apple offers a trade-in program for iPhone. This offers instant in-store credit towards the purchase of an iPhone 7 Plus (or a Gift Card, if trading in via mail) when trading in an iPhone 6s Plus. In the US, the estimated trade-in value of an iPhone 6s Plus is currently $300 (terms apply):

You may also find the iPhone Upgrade Program (also available in selected countries) of interest:

Another option is to sell your iPhone 6s Plus privately and put the proceeds towards your new purchase. If doing so, be sure to follow the steps here:
