I've purchased tires from LBS, Performance Bike shop (~10 miles from home) and also online. Ordering online is by far cheaper than LBS (~40% less) and it only takes a couple of days to receive the goods. I will continue to order tires online unless I am in need of something quick or until LBS prices are within 20% of online prices. I like to support LBS but I don't want to be foolish (about money that is).
