I think it's outrageous that convenience stors sell a bottle of water for a dollar.
But if I had been in the desert for 3 days with no water, I would gladly pay $100 for a bottle.
So it really comes down to - How badly do you need it?
C'mon, do you really
need any of this stuff?

Well, right now, it costs $10 in gas to go to the LHS and back. Shipping on Tower Hobbies is $7.99, or $3.99 for Parts Express items. If I buy all Parts Express items except for one, they will charge the $7.99 shipping. In that case, I'd rather go to the LHS and buy there, since I can get it the same day. If not, I'd gladly order from the LHS and have it shipped there, because they don't charge for shipping, it will probably be there in two days, three days tops, and since I go there so often, I get a 10% discount so essentially whatever I see on the box is what I'll pay. And most of their stuff is below Tower Hobbies or Horizon's prices, given they cannot beat it when you include the online coupons. But its good enough for them to sell me hundreds of dollars in merchandise.
The only thing I have against them for their shipping when I order something from them, it takes 2-3 days to get there, but when Sun_Kissed_Girl orders something, they next day air it at no charge no matter what time the order was placed, and give her anywhere from a 10-20% discount.
