Well, it looks like if you want to support him, you are going to pay more for your items.
You are a very kind and generous person to think about supporting his business.
For me, I would love to support the LBS all the time... but when it comes down to it... my budget comes first.
If I can find it cheaper on the internet and the shipping cost doesn't make it more expensive than if I bought it at the shop... I go for the item off the internet.
Then again... last time I went to my LBS... ready to buy shorts and body glide... they didn't have the items... so I had to take my business elsewhere.
