Wow, Z9 unit cost is halving faster than daily revenue, huge setback for buying earlier batch at premium price for advanced delivery versus waiting/delivery time of newer/cheaper batch.
$1,999 batch 1 has a 2 month head start on both;
$1,520 batch 2 (two being delivered) and
$850 current price
$1,149 price premium over 60 days = $19.15 per day
Current profit @ 10,500 sols = $31-$38 per day
I doubt anyone in batch 1 would take the option of swapping it for two in batch 2 or one @ $850 both being delivered late August.
To everyone saying that batch 1 should have got a 2 for 1;
1. Batch 1 has already shipped for some
2. Batch 1 is limited quantity... how can you double quantity?
3. They want more money spent on a product that isn't meeting their sales expectations... hence coupons.
