Mine says deliver by 4/21. I was looking at my old posts from last year when I pre-ordered the S7 Edge. The original date said ship by 3/11/16, I got mine on the 8th. So maybe we will get them a few days early again this year.
Maybe I've been lucky or things are just quieter in this area. I've bought my last three phones through Best Buy pre-orders, and picked up in store on launch day...worst line I've ever waited was the time I was second in line. Other two, I walked in when the store opened and was out with my phone in 15-20 minutes.
The S8 is actually the first I've pre-ordered online, as it looks like I'll be out of town on the 21st.
I may just change it to Ship anyway... cant do it right now, but as we get close I may ship it to my work. I think they are strict on shipping to anywhere other then the billing address. Verizon will do it but I am not sure if BestBuy will.
