The OBihai coupon policy is implemented to discourage unauthorized "dealer" to buy up all the available stocks and then resell it on the same Amazon page for $85, so OBihai implemented coupon policy to limit 4 OBi110 for $50 and 4 OBi100 for $43 per Amazon account, if you want more than 4 OBi device then you have to pay full list price ($70 per Obi110, $60 per Obi100 if I remember correctly)
