Pixel 7 / Pixel 7 Pro enhanced trade-in credit and promo gift card @ BestBuy

How is Google with the trade-ins? My Galaxy S10+ is in very good shape and Google says $340 for trade-in, but how likely is that? BB only offering $85.
For the Pixel 6a deal, I bought a used 3a ($100) off Swappa and traded it in for 300 credit. It was in good shape, though I never actually used it - just made sure it powered on and factory reset. Google gave me the whole 300 w/in a couple days of receipt. I don't think they're messing around with these trade ins. I had issues with shipping, so make sure you get insurance if you can!
