A:Answer Don't, it is a trick to get you to check in to buying a S20. Most phones over 3 years old can't qualify, so you get nothing. Best buy gets you to sign up for a carrier and or activation and you get to pay full price minus about $50 off full retail. You can only get the $850 off if you trade a new phone like the S10 note with 512 gigs, that's a $1300 phone and you get to trade it for half what you paid last year.
