Keep in mind I'm the other end of the world and things may be different where you are.Theres a casein the news just last week of a "carpetbagger" leaving a total of $300000 owing to customers for goods promised but not delivered -His solution was to declare bankrupcy.It may be fact in your industry but it's not analogous to the dive industry. The major online retailers are not operating with just a computer and a cellphone. They have bigger stores and more inventory than nearly all LDS's.
And please name one large online retailer that has gone out of business. If that is what you're worried about then your risk is 100 times greater with a LDS. I can't count the number of times threads have been started here because someone's LDS closed their doors. There was one just last week that left a couple halfway through OW class, they paid for the class and now can't get their certs and their planned dive vacation is coming up. See Paid for dive lessons, but shop closed up. What do I do?.
Incidently I do agree theres a big difference between companies with an actual shop/inventory who also have a strong internet presence and those with a computer and a cellphone.
I agree totally that if you haven't embraced the internet and don't have your shop/products/services advertised then you are well behind the times.
