Average Loyalty Offer Value?

So, I am currently looking at upgrading my phone via a loyalty offer with Verizon. It seems like these cycle on a roughly monthly basis based on discussions with various service reps, but I was wondering what the average value on the offers tends to be. This one is for $800 on a trade-in of fairly old phones (unfortunately it cuts off just after my oldest working phone, so I likely need to trade in my current phone) and I'm wondering if that is above, at, or below average for the loyalty offers at Verizon.

(The main reason I am not jumping on the deal isn't necessarily that I want more than $800 for the deal, but that they don't currently have a phone with the combination of battery life and storage I'm looking for right now. If this is above average, I might consider sacrificing storage and picking up the new phone anyway though.)
