OnePlus upgrades its trade-in program just before the OnePlus 6 is unveiled
The conditions of the deal/s may have changed since the initial publishing of this post.

With the OnePlus 6 expected to be unveiled a week from today, the company announced an improved trade-in program to help prospective buyers save some cash. After all, the OnePlus 6 will probably be the company's most expensive phone yet; notches and IP certification ratings don't come cheaply, you know. With the new trade-in plan, devices from any manufacturer can be used in a trade, but higher values will be given to those products made by Apple, Samsung, Sony, Huawei and Google.
