Yearly Premium Plus is quite a big investment, but I know that I can't do much of anything within just one month, so I tend to shy away from having more than one Premium Plus avatar. A 3-month long Premium Plus membership would be long enough to, for example, try out a new 2048 LH theme to see if I like it. I just dumped my Mediterranean, tho I wanted to keep it, to try a Tiki. If a 3-month membership had been available, I would have kept the Med and just bought a quarterly PP to try tiki.
