Thank you Paul for taking the trouble to re-investigate the price. Yes, 101 would cost 70p each with free UK P&P. They're a bit more expensive than StarRefills, but you yourself have already acknowledged that the reason is the difference in quality.
The quantity discount applies to the total number of refills in the entire mix, so if you'd ordered say 50 parker types and 51 cross types, you'd still get the cross types at 70p, and the parker types at the 101 price too. Does that make sense? It's explained a lot better on the website.
