Managed to get one on Ebay that finished mid afternoon.
£51 plus postage boxed, non yellowed. Far from a bargain, but cheaper than the usual £70-£80 plus postage they go for.
My justification is I was in hospital yesterday and am feeling a bit sorry for myself

.
I like to go round charity shops, but most will not sell electricals.
I did get Mario 3 and Yoshi's Cookie for a quid each from one though last year and they were boxed too! I did post about them here.
Cash converters in Longton (Stoke) is dire with no good retro stock. It is full of the dregs of society - Jobless, alcoholics, gamblers, all exchanging their latest stolen Xbox. One of the women who works there told me she frequently gets people showing up at opening time absolutely steaming drunk.
Back on topic. I picked up Resistance 3 for £2.49 today pretty good nick.
