Your Cotswold discount will be valid in any branch, as long as you have your membership card (or letter, company ID card, Scout scarf, etc) to prove entitlement. They're getting pretty strict on it, these days.
The Marmot Wave bags in Cotswolds are hard to beat - they are bought in by the truck load, so really good value for money, especially if you bag one in a sale.
