My S9+ was a preorder and is absolutely fabulous so here's to hoping for more pre-order luck for everyone who decides to do this.
I'll probably do the reservation tonight but I don't know if I will go through with it or not.
I think I will go middle of the road and go for the S10. White.
The problem I might run into is my husband will likely also do this. And last time when we tried to preorder the Note 9 together, Samsung refused to process his preorder that was placed after mine, because both of us were doing trade ins.
And they don't accept two trade ins from the same household any more until the first phone is received and processed by them.
To clarify, what happened to us was that they sent him an email telling him his preorder was on hold and would not be processed until the phone I was trading in was received and processed by them. Well my phone was on backorder for weeks, too. He was looking at waiting over a month for a pre-order. Despite iphones being released about a month later, we had our XS-Maxes in hand while people were still waiting on their Note 9 pre-orders.
That got us both so mad along with the long wait for the long backordered model we wanted. I am the one who canceled my pre-order first. As soon as I did that, my husband's hold came off of his preorder but it still remained on backorder even after the opportunity to order the XS Max came up. He cancelled his preorder sometime around the time his XS Max arrived.
I guess I'll go muddle through and look for the fine print and see if they're still at that silly policy again.
Edited for clarity and to update: I can't readily find any prohibition this time on the number of pre-orders with trade-in per household. That doesn't mean it's not buried in there somewhere.
