I've got the complete C64, Amiga, and Atari ST GameBase collections right in front of me, and among the extras are a set of just over 3.300 game adverts, mostly from mags, for C64, Amiga, Atari St, Spectrum, and Amstrad as jpegs, a lot of them stating the prices.
Just a couple of random examples (prices in English Pounds). The tape versions are usually about 5 Pounds cheaper:
Chuckie Egg is marked for 19.95 Pounds (!!) for Amiga and ST
Killed until Dead for C64 and Amstrad at 14.99
Activision Space Shuttle 9.99 (C64)
Melbourne House, The Hobbit 14.99 (C64)
Starglider 17.99 (C64)
Adrian Mole 9.99
and there are loads of cheapos as well, such as special price ranges for just a few quid and cheapo development houses such as Interceptor Software.
If anyone is interested I can offer to upload these to a hoster and pm the links, but it would take a while, as it's almost a Gig in data.
I just had a lot of fun getting a blast from the past with all those old pictures
