I think you’re over-reacting. I’ve done business with MegaHobby in the past and never had issues with their prices as long as I’ve done my price comparisons. Considering you’re bashing MegaHobby for their high prices, it pays to shop around. If you find it cheaper elsewhere, buy there. There’s no need for you to bash MegaHobby.
I’ve seen other online stores more expensive than MegaHobby. Internethobbies.com is one.
