Yes - the original Spectrum came with that Horizons tape, a couple of books, some leads (to connect to your TV and a tape deck) and a power supply.
A bit later on Sinclair bundled more software with it including Chequered flag (motor racing), Chess, Scrabble, Make-a-chip [design logic circuits], VU-3D [a rubbish 3D designer] and Tasword 2 [a word processor]. I think they were trying to make the spectrum look like a more rounded computer than just something for the kids to play games on.
Of course, lots of stores will have done there own deals to shift units. Particularly after the launch debacle which saw WHSmiths getting hundreds of machines returned to them because they didn't work properly and the Sinclair name was mud for a while.
Oh, there is still a thriving Speccy community out there.
