If you missed the 1 day $400 flash sale during BF, this is the best offer right now for the Verizon Pixel 3 and Pixel 3 XL. For those who don't know, Best Buy gives instant discount. The rest is device payment plan. You can pay off 1 week after activation. This is not bill credit.
The way these Best Buy cellphone deals work is as the following:
1. You need to be upgrading a line or starting a new line. If you are upgrading a line that still has remaining device payment, you need to pay it off first. I had to deal with this since I recently upgraded to Note 9 at Best Buy. I had a LG V20 on the line on 2 year monthly installments. I had 2 more installments left. When you pay off the phone, you lose remaining installments. I was able to call Verizon and get it the installments credit back, but it's a YMMV.
2. You will get $300 off instantly, and the remaining will be paid to Verizon on monthly device payment. You can usually pay off the remaining balance in 1 week.
3. You pay tax on MSRP.
4. If you return the phone, you have to pay restocking fee regardless if you opened the phone.
