Well, this is weird...
I placed my order for a 64GB silver 6 Plus at 6:34 AM last Friday, and immediately there was a pre-auth on my debit card for $192-something -- basically, the down payment, SIM starter kit, $24.99 for shipping and sales tax). That charge, naturally, disappeared by Monday or so.
I check order status, but as I'm not an existing T-Mobile customer, I don't have access to the "My T-Mobile" thing, so I think the order status is a little less informative. It has the order date, but no mention of ship date or backorder status or anything useful.
That hasn't changed as of this morning, but now there's a new charge on my debit card from T-Mobile. This one, however is for $37 less than the initial pre-auth. I'm trying to figure out the discrepancy, but coming up short. Even if they removed the $24.99 shipping charge, sales tax isn't that high.
Watch... in a month when my order finally ships, it'll be the wrong phone. Hahaha.
I was able to figure out why I was charged less. See my earlier post. Remember, the tax is charged upfront for the full purchase price of the phone. I'll bet you were charged for the device, plus full tax, less sim and shipping.
