The box-version of Lightroom is still available on the Adobe website or on other dealer, like Amazon.
But Photoshop you can never buy as a perpetual license. You can only buy the Elements versions.
It is available on Amazon.com. I have a similar issue and have contacted Adobe several times with no meaningful resolution. I will reach out to you if I get some productive feedback on my end (not holding my breath). There are also free applications like Gimpshop, Shotwell, PhotoScape, digiKam, and RawTherapee amongst many others, that may fit your needs without trying to rope you into a monthly service charge. This way you'll pay $0 instead of say... $360 over 3 years for a product you'll rarely use and guaranteed you won't find yourself in the same situation again.
Hope this helps!
Lightroom is indeed available in on-line shops.
I managed to buy Photoshop CS 6 boxed in a local book/software store. As I did with the complete suite.
Be carefull - there are some functions in the CC version that aren't available in Photoshop CS6. But as I don't know them ... I don't miss these.
