They've begun updating their website & now have an online shop with full price list, photos of products etc. They'll sell you a whole box of bolts or a single washer & tell me that rather than trying to compete with the big guys who deal in bulk orders, they're aiming for the small, enthusiast market.
One washer can cost as little as a penny, though there's a minimum postage charge of £3.50, so it makes sense to order a few more.
This is a family run business, catering to builders of cars, bikes, boats, vintage vehicles, models etc, as well as local builders & the like. As such they're used to idiots like me wandering in with one knackered, rusty old bolt & asking for a shiney stainless steel replacement. So far, they've never let me down.
As Tony says, if you find good businesses like that, you should support them when you can.
