My best guess is that trade in policy will only be unit for unit within a product category.
Meaning you can only trade in 1 "old" single for 1 "new" single, 1 "old" minirig for 1 "new" minirig. And jalapenos will be sold without any trade ins. This way they will still be getting $$$ flow with every sale or trade in. Mark my words

words marked.
It can be true. They said "full terms of tradein to be announced at a later date" = they can screw you hard if you are stupid and believe their marketing.
