I show up to bike rides all the time with a bike purchased elsewhere. I am from Indiana originally and I bought my bike far east to save money (Chicago prices where I live). I go to these rides at my favorite LBS in MO all the time and I didn't buy my bike there. I didn't buy my bike in Valpo either despite the fact that I do rides there from time to time. I have loyalty to people with good prices and great service. That particular shop in Valpo didn't have the bike in my size and wasn't giving me a reasonable price. Likewise, no one in there seemed to care that I was about 2 grand on a bike. Nothing like crappy service!

I do all my shopping at the local LBS here. I like one better than the other - by far. Generally, the other place is cheaper but the service sucks. Recently, I had to replace my helmet. The good LBS was awesome at trying to make something work, but the helmet they had was too big for my head and the others were no use because they were too expensive for my budget. So, I went to the other store. They had a far better selection of women's helmets.

I always try to support my favorite store first, but it just depends on if they will meet my needs. Recently, I needed a quick fix on my bike and brought it in. The guys there know who I am and have been super in the past about stuff. They asked me if I got a helmet at the other store and I admitted I had and one even said they were trying to bring in another type of women's helmet because people had had trouble with the new style of that model. You might mention to them that they will lose your business. It might make a change.
