Via this WHT offer. XenVZ, the UK provider that offered us 99 pence/month OpenVZ server a few months ago, is having a special at the moment. With coupon code WHT191009-1, you can get the following VPS for £11.97/quater (~£3.99/month).
- 256MB guaranteed/512MB burstable memory (OpenVZ)
- 256MB memory/512MB swap (Xen)
- 20GB storage
- 100GB/month data transfer
- OpenVZ or Xen + in house control panel
I was pretty happy with the performance of my 32MB VPS, although it would be more useful with more memory — so I guess this deal solves the issue. Another good thing is, although US dollar has been crap for the past few months, just remember that Great British Pound is even worse 
Servers are in London, and you get to choose between Xen or OpenVZ servers.
