B + H has the photography package by Adobe (Lightroom and Photoshop) for $99 for the year if you purchase by tomorrow.
Also, Lightroom 5 worked for FREE in Library mode, and version 6 may do the same thing for those that do limited editing.
I use both LR and PS professionally, and for many, Lightroom can now do almost anything most people would ever want to do to a photo. I teach photography here in Italy, and I used to recommend the photography bundle because you needed Photoshop for HDR (or other software) or to do panoramas. Now these are in Lightroom CC and 6.
But historically Lightroom updates every 12-18 months, although this last update came almost 2 years later. If you buy Lightroom and then pay $79 to upgrade to Lightroom 7 within the next 2 years, you will have paid $230, and if you do the 30 day trial and then pay $9.99 a month for BOTH LR and PS, you'll pay $230 over the next 2 years.
Because Adobe has made LR 6 different from LR CC, it is possible that updates won't be frequent with Lightroom 6. I do like Adobe, but I was royally pissed when I paid $199 to upgrade to Photoshop CS6, and then Adobe wanted $49 a month to get the complete Creative Cloud IF I wanted any updates to CS6!
Fortunately the photography package makes getting BOTH programs, PLUS the updates and mobile Lightroom just a bit more than buying Lightroom then keeping it up to date.
Here is Adobe's page on the differences between LR 6 and LR CC:
