Friends don't let friend drink Starbucks. Oops, I mean "shop at Nashbar or Walmart."

I really dislike buying anything from somewhere where the phone reps are completely ignorant of the products and are just collecting a paycheck. The shipping department has a different schedule than customer service and isn't linked to the customer service emails, so if you've made a mistake, give up. It's cheaper in the long run to support your independantly-owned LBS (frequent buyers will get discounts) or a company like TE which has staff that will research the minutia for you and know the products inside and out.
