Have you tried ringing them, just maybe the web isn't set up to deal with this but they may?

I emailed the chap when the website didn't calculate the discount.
Just for clarification, I was ordering several sets of Rotosound Swing bass but they weren't all the same, a couple were 50-110, a couple were 45-105. It meant I paid the price for two sets of two, rather than get the discount for 4 sets, if that makes sense.
This is just a minor quibble and most of the time I would order the same sets anyway so I still use them.
