I have been keeping an eye out for a price drop on this. Checked this morning and they had the standard 20% off (valid for another 11 hours at time of posting).
Using Chrome extension for honey found out that code YTBEN (I have no association with this code) was working to give another 5% off so pulled the trigger (got the 800D4).
Please be careful that the amount is in USD so if you use a credit card most likely you will get international and foreign currency exchange fee. I used a Citibank (you can use Macquire Card too) Card to pay for it as they don't charge any international conversion fee. For me it came to around AUD $575 (approx). I did check PayPal conversion and it was around $600. So just make sure you have the conversion and fee sorted before hand.
All the description about the product can be accessed via Reolink website
This should also work on the 800B4 which is the bullet version but I have not tried it Reolink
Thanks
