In reply to Alpnick:
Good thread.
To throw in my tuppence on your questions:
1. Should we charge Scottish people more?
It's tempting to say "yes, of course - as a matter of principle". I think you should charge as close to *actual* cost as possible for transport. I know it's irrational but I hate shops padding their margin on shipping. So, if you're using a flat rate, charge the same; if you're using a company that costs more for remote areas, differentiate.
2. Pay more for small stuff?
If you have a cost-effective way of sending small stuff, keep using it. If you don't, then perhaps there starts to be changes in SKUs between internet and shops...
3. Wait up to 28 days?
I think next day is over-rated and rarely needed. Why not have it as a premium option? 1-2 weeks is usually fine for climbing gear.
4. Who pays redelivery charges?
The customer. Why should the supplier? The customer can always choose to have it delivered to work, or old Mrs Jones next door or whatever.
Overall, not a huge issue - Royal Mail is fine. Just make sure it's fairly simple, the price is clear up front (so people can make a decision before filling in checkout forms) and you don't take the micky on the charges.
