Well UPS doesn't have my package, so the delivery date is what Samsung says. Samsung says shipped, UPS says they will update when they have the package, so just waiting for UPS to update now, should be right p tonight if they have it
Most likely yours shipping via UPS 2 day air. When Samsung sent the shipped email on Saturday, the estimated date was Feb 6th. I was like no way and it was just a conservative estimate, but when I checked the UPS tracking, I was in for a shock to see it's indeed Feb 6th due to UPS 3 day select.
I have never seen them ship via UPS 3 day select before. All my previous preorders were UPS 2 day air, and I believe the first batch of orders were also UPS 2 day air. I just got unlucky.
I think you should be good for Feb 5th if Samsung estimated that.
