When your new LDS goes out of business as a result of being undercut by internet sales, I hope you can find another LDS.
This is laughable. Why is it always about the LDS? What's wrong saving some of your hard earned money..
Anyway, I'd always ask my LDS if they can match it close to the online price. If they do, then they have my business. If not, I take my business to either Scubatoys or Leisurepro.
