Interesting info, Yu_ & kadamontaga - thanks.
"Time Slip" DOES sound familiar - was that around 1986?
I've noticed that every FP store I've been to in the last few years does seem to have the same logo. I think the Manchester store used to be called Odyssey 7.
I do shop at FP quite often, not out of any particular principle but because one of their stores is close enough to where I work that I've been able to get there pretty much any lunchtime in the last 5 years.
I agree with you that their prices can be quite high - although there are sometimes strangely low-priced items too. I just can't work out their system - but it's always good for a browse, at the very least!
