No they don't have to stop and think.
My money goes to the person with the best price, if the service is good I return.
Its not
all about price!
Will that overseas online store:
- be their on the Friday afternoon when you need spares to get yourself on the water for the weekend?
- support the local juniors, thus growing the sport, through discounts and team rider programs?
- give back anything at all to the local (or national!) kiting community?
After-all, I'm sure whatever you do for a living could be done much cheaper with overseas workers...
Would you be willing to lose your job to skilled imported workers?
