Okay, I think I see where the confusion is. It lies in what is being sold in the LOTRO Store compared to the LOTRO Market. The LOTRO Store and LOTRO Market do not have the same point bundles available. The LOTRO Store (https://www.lotro.com/en/buy-turbine-points) is currently having the double bonus point sale (through Dec 2). It has a $199.99 point bundle which lists the points as:
Double Bonus: 21,000 (Regular bonus: 10,500)
Total: 33,500 (Regular: 23,000)
The LOTRO Market (https://store.lotro.com/en/turbine-points) also has a $199.99 point bundle, but has it listed as:
The double bonus points are only for the point bundles sold in the LOTRO Store. The LOTRO Market does not include the double bonus points (unless they made an announcement somewhere that I missed). While I think the LOTRO Market does have the Base/Bonus points transposed, it does not affect the total points you get (23,000) nor the price you pay for them ($199.99).
