Back in the day it was a lottery win evey sunday near enough (from 1989 to about 1993). I picked up no end of stuff, things that stick out in my mind were:
12" Ben, Leia, and Chewbacca mostly complete for £3
about 2 1/2 to 3 sets of last 15 over 4 years for like pennies
HUNDREDS of boxed vehicles, minirigs, creatures and playsets from 50p to about £10 each
Carded Imperial Dignitary Trilogo for £6
About 10 X 12" Boba Fetts in various stages of completeness 50p to £3
About 4 X 12" Vaders as above
About 3 to 10 or so of each: 12" C3POs, R2 D2s, Stormtroopers
Tons of 70s and 80s toys like Action man, Cyborg and Muton, Dinky and Corgi, 6MDM. all for next to nothing
I never saw 12" Han, Luke, jawa and obviously IG 88 - they were all picked up from fairs, 12" boxed I never saw on bootsales even though my mate picked up luke and fett before I got into it, carded was thin on the ground too.
