UK Postcode issue

Hi there – i’m having this issue, and it never used to be a problem. I can’t submit ranges of UK postcode outcodes (this is the first part of the postcode).

So NR1…NR9 doesn’t work. It has to be

NR1*
NR2*
NR3*
NR4*

…etc

OK? Not quite – the problem with using this wildcard though is that NR1* will include all postcodes that are NR10 and upwards, so NR11, NR12, etc, and these fall within the next shipping zone, as my prices are 0-10 miles, 11-20 miles and so on.

I also don’t think it recognises spaces, so I couldn’t have NR1_, or NR1_1… or could I?

Perhaps there’s another plugin that allows radial distance shipping?

Thanks!
