I have made quite a few orders from Hobby King as well. I expect long shipping times and only order things that I know I will use in several weeks (months?).
Recently I placed an order for some lipos, a charge adapter, some servos and a few other miscellaneous parts. I also wanted an extra batter to fly with immediately. The batteries I ordered from HK were under $6 each. I bought one for immediate use from my LHS (I assure you it is no better than the ones coming from HK) and it cost me over $30 for ONE battery! About the cost, including shipping of my entire HK order!
If you want it fast, you pay the price, if you can wait awhile or anticipate future needs then HK is great for pricing and saving a few bucks.
Just my humble opinion and experience.
