Isn't the Single $633 and the upgrade $733?
you are correct. i got my numbers mixed up. my SC single was $1333. the upgrade was $733.
Just trying to clarify here since you keep saying different numbers and using the term "upgrade"
If you bought the FPGA single for $633 and upgrade for $733, then you paid total $1366 and will be required to send in the FPGA single before they ship you SC single. End buyer will be left with 1 SC single.
Or are you saying you bought one FPGA single ($633), one SC upgrade ($733), one SC single ($1333), so end buyer will end up have two SC single after return of FPGA?
Neither way makes sense really. One way buyer is paying an extra $1,100, the other way you are losing a couple hundred dollars.
OR 2 spots in line? Buyer get's nothing but already paid for places in line. Buyer would have to send in a FPGA to get the upgrade price. That's the only way it makes sense but you said they already shipped your single. Then claim to paid $1333 for your single (that doesn't exist yet) and $733 for upgrade.
