If you're going to do this, at least see if your LBS will either match or get near the online price + delivery. It's a bit cheeky to try things out then not even attempt to spend money with them. FWIW,
Evans will price match to online stores, which is how I got my shoes. While there's many items (for cycling and other sports) I'd buy online I draw the line at shoes and gloves. They're a pretty important contact point, sensitive to comfort (or lack of) and I've had too many pairs of shoes/gloves that were mis-sized, mis-shapen and badly made to buy blind.
