With a simple phone call, a household would have dinner planned for the week or enough milk to cover breakfast and lunch for the same amount of time.
Merchants sold goods and services, yes, but what they towards was establishing a relationship - one that benefitted both.
Finding a reliable shop today is based on the same principles and has the same benefits. A good shop will provide reliable service backed by a complete knowledge of the products they sell. At the same time, they will understand how you ride and will offer products to suit your riding style.
When looking for a good shop, keep a few goals in mind. Remember too you'll need to work with a shop until they understand how you like to ride and maintain your equipment, and most importantly, advance your abilities without overselling you. Ask questions, test their knowledge and need to be helpful.
