Just received a poa base set to find a few missing

I've been in contact with the seller and they cant help. She was quite happy to refund me, but frankly, by the time I send them back, as I bought them in US, then buy another set, Im gonna be out of pocket by a bit. Its just not worth going that route, especially as these sets are really hard to come by now, I've found.
So.....to cut a long story short I was wondering if anyone had these as spares somewhere?
No. 67, 68, 69 & 72.
If anyone can help let me know how much.
Muchly appreciated
