Also; any particular reason for the pricing? B1 with 3 modules was about 1350 USD, you are asking 890 for a single module.
Will you sell me your 3 modules Avalon batch 1 for 1350 USD, or even 2000 USD?
I'm willing to fetch it (almost) anywhere in the world for that price.
If your answer is "no", then you should be able to answer your own question too

Supply and demand...
