I presume the £22.30 per year is 3 years for price of 2 lease deal only available to V8 owners (but you have to pay up front).
At the end of three years, you can revert to V8 or get a new lease of VX.
However, there is no guarantee you would get the 3 for 2 deal thereafter and cost could increase to c. £36 pa.
The alternative is trade in the V8 but get 50% off in perpetuity.
I am unaware of any offers that are better than the above - indeed the Macrium FAQs guarantee the offers beat any Black Friday deal.
So
1) 50% discount lease -
PRO guaranteed discount for life (provided you always pay lease - you cannot skip a year).
CON cannot revert back to V8 if you decide not to pay leases anymore
2) Go for 3 for 2 lease
PRO - you can revert to V8 at end of 3 years, Not much dearer than (1) above for 1st three years
CON - no guarantees on future deals (worst case is paying 100% of lease).
As I had 1 single licence of V8 and a 4 pack licence of V8, I decided to trade in the single lease, accepting that if I did not renew, I would only have the four pack V8 licence (no big deal as I never used all the 4 licences in the 4 pack (plus I still have 4 V7 licences). So in my case, it was a no brainer.
I could have traded in the 4 licence pack for c. £36 per year but I rarely use the leases much (few times a year at most), so elected to stay on V8.
If you only have a single V8 licence, the 3 for 2 lease is a pretty safe deal in the short term (1st 3 years) as you are able to revert if you decide a lease is too costly long term for you (especially as you may not get a good deal after 3 years).
No matter how you look at it, the 3 for 2 deal (even if repeated) works out dearer than the straight 50% but you do get to keep the V8 licence. I do not know if you can use the V8 licence at same time (
@Bree is pretty good on this stuff).
OK a longish reply but in simple terms, no offers ever better the above as that is their sweetener guarantee to existing V8 licence holders.

Of course, one could just stay on V8 at no cost, but there is a theoretical risk that one day V8 would not work e.g. due to a Windows change, but I believe the company's integrity would not allow them to leave all existing V8 licence holders in a position they could not use it any more. and they would issue a fix. Of course, that is purely personal opinion. I had such a situation with Acronis with a bug making my version unusable, but they only fixed it for the next major update, insisting I would have to pay. I (and I suspect many others) voted with their feet and went elsewhere (hence why I became a Reflect user).
Of course, many will say there are plenty of free quality alternatives, but I have NEVER been letdown by Macrium Reflect and to me, £18.49 per year (c. 3 pints of Stella per year) is peanuts for the peace of mind,
and good service. Indeed I had an issue a few days ago where VX kept forgetting my lease and I had to click a popup to "transfer lease" to pc. Within 3 days (including weekend), I was given a registry edit fix that sorted the issue. None of the free versions (and paid versions) of other tools comes close to this level of support service. In simple terms, as my dear old Gran used to say "You get what you pay for".
